Answer:
y = ½x + 10
Step-by-step explanation:
Perpendicular lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>[<em>Slopes</em>], so you need to have a slope of ½, like in the work shown below:
9 = ½[-2] + b
-1
10 = b

**I have a video that explains how to find the y-intercept, Perpendicular Equations, and Parallel Equations. All these words are in the title. I encourage you to watch the video and gain alot more knowledge from it, so you can better understand the concept.
Answer:
3x2y−3xy+12x−12
Take out 3xy common from first two terms and 12 from last two terms.
3xy(x−1)+12(x−1)
(x−1)(3xy+12)
