Answer 3

change it to slope intercept equation y=mx+b
b=y-int
m=slope

Answer 4

to calculate for slope: \[m=\frac{ \Delta y }{ \Delta x }=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]

Answer 5

using the given coordinates calculate for b

Answer 6

So I substitute the variables for the coordinates?

Answer 7

kinda...?

Answer 8

\[\frac{ -1 - 5 }{ -4 - 4 }\]

Answer 9

Like that?
