Answer:
m = 20
Linear
Linear
Step-by-step explanation:
m is the slope and we can find the slope by using the equation [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex].
(45-25)/(1-0) = 20/1 = 20
Since the slope is constant throughout the whole data point (increased by 20 when x is changed by 1), we know that this is linear.
Same with option 3.
