Point-slope form worksheet
The form is y - y1 = m(x - x1): the slope, and one point the line goes through, copied into their places. Easy and medium give both. Hard gives two points, so the slope has to be worked out first, and either point can then be used.

How to do these
Write the point-slope form of the line through with slope
- The point is (x1, y1), so x1 = 3 and y1 = -2.
- Copy them in: y - (-2) = 4(x - 3).
- Tidy the double sign.
The answer is .
Where students go wrong
Flipping the signs. The form subtracts the coordinates, so a point with a negative coordinate turns into a plus: through (3, -2) it is y + 2, not y - 2.
Also called point slope form, y - y1 = m(x - x1) or equation from a point and a slope.
