Due by tomorrow and i have no idea how to do it

(1) See figure attached

(2) y = 0.12*x + 0.2

(3) $2

(4) 11 minutes

Step-by-step explanation:

(1)

To make the graph, plot point by point and connect them with a line.

(2)

To get a line's equation you need its slope (m) and its y-intercept (b), because equation form is y = m*x + b.  

Knowing 2 points of the line, (x1, y1) and (x2, y2), slope is computed as

m = (y2 -y1)/(x2 - x1)

Replacing with (1, 0.32) (2, 0.44) it gives

m = (0.44 - 0.32)/(2 - 1)

m = 0.12

Know you have the slope, you can get b substituting 1 point in the general equation. Using point (1, 0.32) gives

0.32 = 0.12*1 + b.

b = 0.32 - 0.12*1

b = 0.2

So, the equation is y = 0.12*x + 0.2

(3)

Equation gotten in the previous part of the exercise relate y (cost of the call) with x (number of minutes). So, if you replace x = 15 minutes, then you will get call cost in $.

y = 0.12*15 + 0.2  

y = 2

(4)

In an analogous way as before, you have to replace y = $1.52 and isolate x (which is in minutes).

1.52 = 0.12*x + 0.2

0.12*x = 1.52 - 0.2  

x = 1.32/0.12

x = 11
