Question

Write the inequality in slope-intercept form: 9x - 3y > 12

Answer 1

Slope intercept is a fancy way of saying "equation of line": y = mx + b.
However, this is an inequality, so our equal sign will simply be a greater than or less than symbol.

9x - 3y > 12
-3y > -9x + 12

Now when we divide by -3, we need to flip the greater than sign to a less than sign.

y < 3x - 4
