Answer:
Step-by-step explanation:
y=5x-2
slope of the line is 5 because if we compare to
y=mx+b where m is the slope we see m=5
Points (0,-2), (2,8), (4,18)
slope between the points (0,-2), (2,8)
m=(y2-y1)/(x2-x1) = -2-8/0-2 = -10/-2 = 5
slope between the points (4,18), (2,8)
m=(y2-y1)/(x2-x1) = 18-8/4-2 = 10/2=5
slope between the points (4,18), (0,-2)
m=(y2-y1)/(x2-x1) = 18+2/4-0= 20/4 =5
