Question

Write the slope-intercept form of the equation of each line.

8x + 3y = -9

this is becoming a serious problem. my math teacher CANNOT teach.

please help.

Answer 1

`y=-(8)/(3) x - 3`

Explanation:

Slope-intercept form is y = mx + b.

You are given 8x + 3y = -9, so to convert this into slope-intercept form you would solve for y and rearrange the terms (if needed) to follow the format of mx + b.

Start by subtracting 8x from both sides of the equation.

3y = -9 - 8x

Divide both sides by 3 to isolate y.

y = -3 - 8/3x

Rearrange the terms so the "x" variable is first.

y = -8/3x - 3
