Question

How do you fnd the slope of a line parallel to the graph of each equation `y=4x`?

Answer 1

The slope of all lines parallel to `y=4x` is `4`.

Explanation:

All parallel lines have the same slope.

Any line in the form `y=mx+b` is in slope-intercept form with a slope of `m` and a y-intercept of `b`.

Writing `y=4x` as `y=4x+0` lets us consider the equation to be in slope-intercept form
with a slope of `4`.
