Question

Determine whether each function is linear or nonlinear

1. 2x(5+x)=y
2. Y=7x+15
3. X/y=8

Answer 1

1.This function is linear.

2.This function is linear.

3.This function is nonlinear.

Answer 2

Answers

1. Is Non- linear because when you multiply you get x^2 which is a quadratic function and not linear

2. Is Linear - it is in slope intercept form which is linear

3. Is linear, it can be changed to slope intercept form which is linear, (y= 1/8x)

I graphed these to prove my assessment of which are linear and nonlinear
