Answer:
linear
Explanation:
For each increase of 1 in x, we decrease 2 in y
The slope is -2
It has a constant slope for all the points
There fore it is linear
We know the slope and the y intercept( when x=0, y =-3)
y = mx+b
y = -2x -3
We can check by picking a random point and verifying
(2,-7)
-7 = -2(2) -3
-7 = -4-3
-7=-7
