The first table on the list:
x 1 Â 2 Â 3 Â 4 Â Â 5
y 5 10 15 20 25
Step-by-step explanation:
A linear equation is when the slope is the exact same between each point. Â The way we find slope is by finding the change in "y" over the change in "x".
x-values: 1, 2/y-values: 5, 10---=5/1=5
x-values: 2, 3/y-values: 10, 15---=5/1=5
x-values: 3, 4/y-vaues: 15, 20---=5/1=5
x-values: 4, 5/y-values: 20, 25---=5/1=5
The slope for each change in points is 5, which means that this table represents a linear function.
