Writing in Point Slope form

You need:

A Point ( x₁ , y₁ )

A Slope m

Worksheet

Work on numbers 1-12

Remember: you need a slope (m) and the point ( x_{1 ,} y₁ )

Point Slope to Standard Form

y - y₁= m ( x - x₁ ) into Ax + By = C

SOLVE to transform from point slope to standard form

Worksheet

Work on numbers 1-6

Remember: to transfer from point slope to standard form, solve the equation and make balanced moves so your X and Y are on the left side of the = sign and the C is on the right.
