Question

Is y = 0.5x - 1 a liner function

Answer 1

$\text{Yes, it is a linear function}\\\\\text{The reason why it's a linear function is because there is a constant change}\\\\\text{The constant change would be your slope, and the slope in this case}\\\text{is 0.5}\\\\\text{If you plug this equation in a graph, it would be a straight line forever}\\\\\text{If you want to know if a line is linear, just check the slope to see if it's}\\\text{constant.}$

Answer 2

Slope intercept form is y=mx+b. Any equation in this form is linear.

Step-by-step explanation:

if it was x squared it is not linear, its quadratic, so if there is ever an equation with just an x its linear. any x that has an exponent that's is not 1 is not linear. Hope this makes sense.
