Draw a line through the origin that has a slope of negative 2/5

The answer is on the picture below. If you need help with graphing i recommend a website call demos. You can put the function in and it will show you the line or slope of the equation. Please tell me if you need help, and ask if you have anymore questions.

As long as the slope (m) is -2/5, b can be anything. For example:

y = mx + b, in which m = -2/5

I can write an equation as:

y = (-2/5)x + 5

In which the line will look like the attached picture:

i think the amount would be $140.62

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
