Question

How do you find an equation of the line containing the given pair of points (-5,-4) and (-9,-1)

Answer 1

The equation of a line is is the form of y=mx+b
Where m is slope and b in the y intercept.

Answer 2

First thing to do is find the slope!

Slope=\[\frac{ y1-y2 }{ x1-x2 }\]

Answer 3

After you find slope, you'd find the y-intercept by plugging in a pair of points into the equation. Example: (-5, -4) plugged into this equation : y = x + b
-4 = (slope)(-5) + b
