Answer:
linear
Explanation:
this is a linear function!
linear functions follow y = mx+b, where m is the slope and b is the y-intercept
let's write our y = mx+b equation
for each value that x increases, y increases by DOUBLE that amount. slope is y/x, so since y increases by 2 and x increases by 1, the slope is 2/1 which is 2.
the y-intercept is where the line passes the x axis, or when x is 0. in this table, it gives you your y-intercept, which is -6
your equation is y=2x+(-6); which simplified to y=2x-6
if you plug in the y and x values, you'll get the same thing. i hope this helped!
