Answer 2

Finding the equation of a line:
Recall that -->

\[y=mx+b\]
m= slope of line
b= y-intercept
Looking at this graph.... They give you two points.
(-3,4) & (-1,-5)

Step 1: Find Slope-->
\[m=\frac{ y2-y1 }{ x2-x1 }\]
Plug in points***
\[m=\frac{ (-5)-(4) }{ (-1)-(-3)}\]
m= -4.5

y=-4.5x+b **
Solve for b --> Plug in point

-5=-4.5(-1)+b
b=-9.5

so:
\[y=-4.5x-9.5\]
