Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.
I'm bad at transitions so here's the math:
(y2-y1)/(x2-x1)
((-10)-(-9))/(4-2)
-1/2 ------> Thats "m".
SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE
The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.
Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.
y=mx+b
m=-1/2
b=-8
y=-1/2x+-8-----> y=-1/2x-8

Answer:
<A = 115 degrees, <C = 50 degrees
Step-by-step explanation:
<A+<B+<C = 180 degrees
substitute with the given values: 4x - 13 + 15 + x + 18 = 180 degrees
Solve: x = 32 degrees
Substitute back in for <A : 4(32) - 13 = 115 degrees
Substitute back in for <C: 32 + 18 = 50 degrees

Last Week, Angus studied for 6 1/3 hours. This week. he plans to study 1/2 as much as he studied last week. How many hours does Angus plan to study this week?
Answer:
3 1/6
Step-by-step explanation: I multiplied 6 1/3 and 1/2 together and I got 19/6
19/6 is an improper fraction so you would divide 19 divided by 6 would give you 3 1/6!
Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?
Answer:18.3
Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3
Answer:
$315.68
Step-by-step explanation:
We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.
a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.
Answer:
Equation: y=(-1/20)x+12.
Slope: -1/20
Y-intercept: (0, 12)
Step-by-step explanation:
Let x=the number of gallons of gas in Christopher's car.
If we start with 12 gallons, we have the equation: y=(-1/20)x+12.
This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).
Let me know if this helps!

Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)
Answer:liz scored better
Step-by-step explanation:
Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

Which set of number shows a proportional relationship?
Answer:
D
Step-by-step explanation:
Find the scale factor that was used in the dilation shown.
The scale factor that was used in the dilation could be 1.5 units.
What is scale factor?Suppose a figure (pre image) is dilated (dilated image) by scale factor of k. So, if a side of the figure is of length L units, and that of its similar figure is of M units, then:
L = k × M
where 'k' will be called as scale factor.
The quantities that are squares or multiple of linear things twice grow by square of scale factor.
So area of first figure = k² × area of second figure
Similarly,
The Volume of first figure = k³ × volume of second figure.
Since the scaling is done by product of some constant, that constant is called scale factor.
Then we have:
K = 4/6
K = 2/3
K = 1.5 units.
Thus, scale factor is the ratio of the new measurement to the old measurement therefore, the scale factor that was used in the dilation could be 1.5 units.

Answer:
It is equal to -8 cuz...
Step-by-step explanation:
(-3) - 5 is -8 how it's cuz a negative number minus a positive number it's gonna be a negative number.
but if a positive number minus a negative number it's gonna be a positive number.
and a negative number minus a negative number it's gonna be a positive number.
