Linear or non linear? pls help

A. no  B. no  C. yes   D. yes   E. no   F, no   G. no   H. yes   I. no

Step-by-step explanation:

The graph of a linear equation must be a straight line.

If you calculate the slope between coordinates and it is the same for all items in the chart, the function is linear. if it changes, it is a curve, not a straight line.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
