Amy began with $28 in her bank account and spent $2 each day. The line models the amount of money in her bank account. She incorrectly wrote an equation for the line in slope-intercept form as y=−2x+14. What is the correct equation for the line in slope-intercept form? What mistake might Amy have made?
PLEASE HELP!!
Answer:
y = -2x + 28
Step-by-step explanation:
In the graph, where the line intercepts the y axis is at 28.
Amy could've gotten this incorrect because she could've assumed the y-int to actually be the x-int, which is 14.
Because of this, she got the equation of her line incorrect.

Your state lottery is offering a choice of pay out options with the next Powerball drawing. Winners of the Powerball can choose between 1 billion dollars or they may choose to start with $2 on day one, double it the next day to $4, double it again the third day to $8, and so on for a term of 30 days.
a) Create a chart to help you find a pattern in the second payout option then write a formula.
b) Which payout option would you choose? Show all your calculations and explain which choice you would make.
c) How much money would you have if the term was 45 days? Express your answer in both standard and scientific notation.
The graph models the linear relationship between the temperature of Earth's atmosphere and the altitude above sea level. Earth's Atmosphere Which of these best represents the rate of change of the temperature with respect to altitude? -6.5°C/km -3.5°C/km -0.29°C/km -0.15°C/km
Answer:
A. -6.5°C/km
Step-by-step explanation:
It's easier to find slope if we can locate two points.
Looking at the graph, it looks like it passes through the points (4, -10) and (7,-30).
To find the slope, we divide the difference of the y-coordinates by the difference of the x-coordinates. Here, the difference in the y-coordinates is:
-10 - (-30) = -10 + 30 = 20
The difference in the x-coordinates is:
4 - 7 = -3
So, the slope is:
20/(-3) = -20/3 ≈ -6.67
This is the closest to the first answer choice, -6.5°C/km, so that is the answer.

In slope-intercept form, write the equation of the line that passes through points (-7, 8) and (2, -2).
Use an algebraic approach and show your work in order to earn full credit.
Answer:
y = -1x + 0.5
Step-by-step explanation:
First, I plotted the points (-7, 8) and (2, -2). Then, I drew a line connecting the two points. At the point (-7, 8), I went down 2 squares and to the right 2. This would give me a slope of -1. Since the line touches the y-axis at 0.5, this is the y-intercept.
I am not sure about the y-intercept of this equation. If I got this wrong, I am sorry and please let me know. Thank you!

y = -1x + 0.5

On a coordinate plane, 2 straight lines are shown. The first solid line is horizontal to the y-axis at y = negative 1. Everything above the line is shaded. The second dashed line has a positive slope and goes through (0, negative 4) and (2, negative 2). Everything below and to the right of the line is shaded.

Please help I really don't get it
Answer:
of in math means multiply so I would assume its asking you to multiply 5/7 and 1/7. that would give you 28/3 which simplified gives you 7.
the missing part in the given equation is 1/5
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given 5/7 of ... is 1/7
Let the missing number be x
of in the given sentence means multiplication
Multiplication is a method of finding the product of two or more numbers
5/7x=1/7
Divide both sides by 5/7
x=(1/7)/(5/7)
x=1/7×7/5
