Answer:
3
Step-by-step explanation:
slope = y2-y1/x2-x1
slope = (20-5)/(9-4)
slope = 15/5 = 3
Rearranging the equation gives us y=15-3x
if we were to find an equation for a PARALLEL line, we would just use the same slope.
if we were to find an equation for a PERPENDICULAR line, we would do the opposite reciprocal. in this case, that would be answer D. but this is WRONG!
the question asks us to find the slope of a PARALLEL line. thus, the answer is C.
final answer -- C.
Answer:D
Step-by-step explanation:
(3x+6)(3x+6) =9x^2+18x+18x+36=9x^2+36x+36
