Question

8.) write in standard form a line

perpendicular to
y=-1/3x +2
Passes through (9,-12)

Answer 1

-3x + y = -39

Explanation:

If it is perpendicular to y=-1/3x+2, then the slope is positive 3. If it passes through (9, -12), then we can set up our equation:

y+12 / x-9 = 3. Simplifying, we have:

y=3x-39, which in standard form is:

-3x+y= -39

Hope this helps!
