Question

For #3 find the x and y-intercept and graph​

Answer 1

Answer: x-intercept is (-8,0) and y-intercept is (0,-5)

Explanation:

5x+8y=-40

To find the x-intercept, you plug in 0 in for y.

5x+8(0)=-40

5x=-40

Then solve for x

5x/5=-40/5

x=-8

The x-intercept is (-8,0)

To find the y-intercept, you plug in 0 in for x

5(0)+8y=-40

8y=-40

Solve for y

8y/8=-40/8

y=-5

y-intercept is (0,-5)

Answer 2

The x-intercept is at -8 and the y-intercept is at -5.

Explanation:

When you simplify 5x + 8y = 40 into y = mx + b form, you get y = -5/8x - 5.
