Question

Write the equation 4x + 8y = -24 in slope-intercept form. Then graph the equation. O None of the other answers are correct

Answer 1

4x + 8y = - 24

8y = -4x - 24

divide both sides by 8

y = -1/2x - 3

`y\text{ = }(-1)/(2)x\text{ - 3}`

Using y = mx + c

To obtain y intercept, make x = 0

so y = -1/2(0) -3

y = -3

(0,-3)

To obtain x intercept, make y = 0

so that 0 = -1/2x -3

1/2x = -3

x = -6

(-6,0)

Taking the points (0,-3) and (-6,0) to plot the graph
