Question

Put the following equation of a line into slope-intercept form, simplifying all fractions. 9z+ 3y = -9​

Answer 1

y = -3z - 3

Explanation:

y=mz+b ==> slope-intercept form where m=slope

9z + 3y = -9​

9z - 9z + 3y = -9z - 9 ==> solve for y

3y = -9z - 9

(3y = -9z - 9)/3 ==> divide equation by 3 to isolate y

y = -3z - 3
