Answer:
a) Function 3
b) Functions 1, 2 and 4
c) Function 2
Explanation:
a:
Function 3 has a y-intercept of -5. It is the furthest away from 0. Function 1's y-intercept is 4
Function 2's y-intercept is 2
Function 4's y-intercept is -3
b:
All of the functions' y-intercepts are great than -4 expect for 3's which is -5
c:
The larger the slope, the steeper the line.
Slopes:
1) -1
2) 5
3) -4
4) 3
The slope is the change in y over the change in x.
