Answer:
- The y-intercept is (0, 8)
-----------------------------------
According the the table the slope is:
- m = (12 - 4)/(1 - (-1)) = 8/2 = 4
Use slope-intercept form:
- y = mx + b, where b is the y-intercept
And substitute one of the ordered pairs, to find the value of b:
- 4 = 4(-1) + b
- 4 = - 4 + b
- b = 4 + 4
- b = 8
The y-intercept is (0, 8).
