Question

Can someone create an equation with this information?:
x: 5 y: 4
10 40
15 76
20 112

Answer 1

let's see..
x1=5, y1=4
x2=10, y2=40
M = (40-4)/(10-5) = 36/5

Answer 2

y-4=(36/5)(x-5)
y = 36x/5 - 32

Answer 3

now let's check if it works

Answer 4

36*10/5 - 32 = 40
36*15/5 - 32 = 76.. etc, it works!

Answer 5

y=36(10)/5 - 32
y=360/5 - 32
y=72-42
y=40
Thank you sir =)
