So you would cross multiply the numbers.
So
m x 15 and 10 x 12
It would be set up as:
15m = 120
Just divide 15 on both sides
m = 8
There ain’t no answer choices ?
Point-slope form is y - y1 = m(x - x1). If you apply that point and the slope to the formula (hence the name point-slope), you'd get y - 10 = -5(x + 8).
Hope this helps! :)
REVISE: I accidently put y instead of x in the -5(x + 8) part. It's fixed now.
23 sevenths
or 3.2857.....
I think it is because if you divide by a negative you which the sign ?
