Question

Which of the following equations show the relationship between x and y in the table?

1. y= x+3
2. Y= 3x+1
3. Y=2x+2
4.y=4x

Answer 1

y=2x+2

Explanation:

you have to substitute x and y in the given equations and which one works

for y=x+3 , 4=1+3 true , 6=2+3 false

for y=3x+1, 4=3*1+3 false

for y=2x+2, 4= 2*1+2 true, 6= 2*2+2 true, 8= 2*3+2 true, 10=2*4+2 true

for y=4x, 4=4*1 true, 6= 4*2 false
