f(x) = 4x-4
1) We've been told that point (3,8) belongs to another line and that's parallel to y=4x-7
2) Parallel lines share the slope. So we can write that
m=4 for the parallel line.
2.2) Now we can plug into the slope-intercept form the given point:
(3, 8)
y=mx + b
8=4(3) +b
8=12 +b
8-12 =b
b = -4 So the linear coefficient of that parallel line is -4
3) So, we can write it out this parallel line as described by the following function:
f(x) = 4x-4
