If line A is parallel to line B, then line A and line B have the same slope.
Since the line is parallel to y = 4x + 2, then the slope of the line is 4
**To take it a step further, let's find an equation for this line.
Since we know the slope is 4 and it passes through (6,-7), then we can solve for b in our y = mx + b formula where
m = 4
x = 6
y = -7
y = 4x + b
-7 = 4(6) + b
-7 = 24 + b
b = -31
Therefore, our equation is y = 4x - 31
Plug in y = 4x + 2 and y = 4x - 31 at wolframalpha.com to see the results yourself.
