Y=x^2-8 is linear or nonlinear

Nonlinear.

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

We notice that if the line is linear, x will NOT go over a degree of 1.

x² is a quadratic function, and its slope is not proportional like a linear line.

correct answers below:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
