  1. Find the slope of the line through the points (6, –8) and (3, –4). Homework Help ✎

    1. Use the point-slope formula to find the equation of the line through (6, –8) and (3, –4).

    2. Is the point (–3, 4) on the line you found in part (a)? How can you tell?

yk = m(xh)
Where (h, k) is a point on the line and m is the slope.

Substitute the coordinates into the equation to see if the point is on the line.
