x | y
3| 2
5 | 6
7 | 10
A)
1) Locating the points, we can see that to each coordinate of x corresponds the following y-coordinate:
x | y
3| 2
5 | 6
7 | 10
2) Let's find out the rule for that function. Picking two points of that function: (2,0) and (3,2) plugging into the slope formula
and replacing point (2,0) and the slope into the slope-intercept formula we have:
(2,0)
y=mx +b
0=2(2) +b
0=4 +b
-4 =b
3) Hence, the rule of that function is f(x) = 2x -4 examining the option we have as the answer A
