Question

Which equation represents a line that has a slope of 4 and passes through the point (3,-8)?

Answer 1

The equation of this line would be y + 8 = 4(x - 3)

Explanation:

In order to get this we can start with the base form of point-slope.

y - y1 = m(x - x1)

Now that we've got this, we can plug in the slope for m. We can also plug in the point for (x1, y1).

y + 8 = 4(x - 3)
