Use the slope formula and slope-intercept form
y=mx+b
to find the equation.
y=2/11x + 4/11
Hope this helps
C is the answer by using distributive property
Y=(x+1)(x-1) this is factored out
Y=4x-14 to find the slope you need to do
rise/run and to find b you need to see where the line crosses the y axis
