Question

Type the equation that shows the pattern among this set of ordered pairs. (2, 4), (3, 8), (4, 12), (5, 16)

Answer 1

y=mx+b
m=slope
b=yint

slope=(y2-y1)/(x2-x1)
(2,4) (3,8)
Slope=(8-4)/(3-2)=4/1=4

y=4x+b
(x,y)
(2,4)
4=4(2)+b
4=8+b
-4=b

y=4x-4

Answer 2

x + 1 y +4 and the next number would be (6, 20)
