Question

An equation of a line through (3, 10) which is parallel to the line y = 5x + 4 has slope:

And y-intercept at:

Answer 1

Parallel lines have the same slope, so the slope is 5.

The equation in point-slope form is y-10=5(x-3). Substituting x=0, we get y - 10 = -15, and thus the y intercept is (0, -5).
