PLEASE HELP DUE VERY SOON!

Answers

Answer:

Yes. (see below)

Step-by-step explanation:

First, find the slope of the line. You can do that by using the slope formula:

      y2 - y1

m = ----------

      x2 - x1

Now, choose any two points from the line to plug in. I'm using the points (0, 3) and (2, 4).

      4 - 3

m = ------

      2 - 0

      1

m = --- = 1/2

      2

Now, to simplify your situation, you can use the slope-intercept formula. To use this, you first need to find the slope and y-intercept.

The y-intercept is where the line meets the y-axis, which is (0, 3), so the y-intercept is 3.

Now, plug them in:

y = mx + b

y = 1/2x + 3

To see if a specific point is on this line—which, in this case, is (20, 13), plug them in and simplify to see if it's true:

13 = 1/2 (20) + 3

13 = 10 + 3

13 = 13

This is true, so the point (20, 13) is on this line.

Mrs. Rogers sold 48 out of 80 crafts at the fair. What percent of her crafts did she sell? ~Plz answer like ASAP!!thank you :)) ~

Answers

Answer:

38.4

38.4 is 48% of 80

Step-by-step explanation:

What is 48% of 80?

Y is 48% of 80

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 48% * 80

Converting percent to decimal:

p = 48%/100 = 0.48

Y = 0.48 * 80

Y = 38.4
