Question

Write an equation in point-slope form for the line with a slope of -9 that passes through (-1,-3)

Answer 1

Answer:

$y+3=-9(x+1)$

Step-by-step explanation:

The formula for point slope is: $y-y1=m(x-x1)$

When:

m = slope

(x1,y1) = the point on the graph

-9 is the slope, so it replaces m. x1 is -1, and y1 is -3.

Plug in the values:

$y-(-3)=-9(x-(-1))$ OR $y+3=-9(x+1)$
