The answer should be A, if he marked it up 70% just multiply 66 by 1.7 for your answer.
Answer: -2
In order to find the slope of this equation you must put it into slope form which is y=mx+b
Solved: y= -2+5
M is the slope
Use the point slope formula. then, substitute the values inside the formula.
x1 =3
y1= -2
m = 23
y -y1 = m ( x - x1)
y - (-2) = 23 (x - 3)
y + 2 = 23 ( x - 3)
