y=-2x +2
1) Let's pick two points from that table: (0,2) and (1,0) and then plug them into the slope formula:
2) Now that we know the slope, let's plug that into the slope-intercept formula to find out the value of the linear coefficient (b)
(0,2)
y=mx +b
2=-2(0)+b
b=2
3) Hence, we can write that linear function as: y=-2x +2
