Answer:
y=4/3y -9
Step-by-step explanation:
just divide both sides of the equation by 3
We know <em>a </em>is perpendicular <em>l</em> and that perpendicular means 90 degrees. Using corresponding angles, we know that <em>angle 3</em> also is 90 degrees. Using corresponding angles again, was know <em>angle b</em> is 90 degrees. Since 90 degrees is the same thing as perpendicular this would mean that <em>line b</em> is perpendicular to <em>line</em> <em>m</em>.<em />
