Given the equation:

9x - 6y = -72

Write in slope-intercept form.

Solution:

In order to write the given equation in slope-intercept form, we must take note of the equation of slope-intercept form.

y =mx + b

Hence we must solve for y in order to equate the given equation into slope-intercept form.

9x - 6y = -72

Transpose -72 and -6y on the opposite sides of the equation, hence it must be taken to note that in transposing a number, the sign changes.

6y = 9x + 72

Divide both sides by 6 to cancel out 6y, leaving behind y

6y/6 = (9x + 72)/6

y = 3/2x + 12

Final answer:

y = 3/2x + 12
