A line equation can be written in slope intercept form, which is
Where m represents the slope and b the y-intercept.
For our first problem, we have a line that passes through the point (0, 8) and has a slope equals to 3.
If we substitute this slope value on the form presented, we're going to have
If we evaluate our point on this form, we're going to find our missing coefficient b.
The line equation with slope equals to 3 that passes through (0, 8) is
