Question

A line passes through (2, 8) and (4, 12). Which equation best represents the line? (10 points)

y = 1 over 2 x + 6

y = 2x + 7

y = 2x + 4

y = 1 over 2 x + 10

Answer 1

Answer: y=2x+4

You first find slope which is y2-y1 divided by x2-x1 that gives you slope and then you put it into the formula y-y1=m(x-x1)
