a line contains the points (1,-8) and (-2,-7)

Answer:
y= mx+b the answer is y= -1/3x +-8
Step-by-step explanation:
the points are (1,-8) and (-2,-7)
to find the slope you use this formula y2-y1 over x2-x1
So -7 - -8 over -2-1. the answer to that is 1 over -3 so u make the whole fraction - so it is - 1/3.
then u put it into slope intercept form. y=- 1/3x+ -8
