The formula
m = (y₂ − y₁) / (x₂ − x₁)
"Rise over run." Positive slope goes up to the right, negative goes down. Slope of 0 is a horizontal line; an undefined (infinite) slope is a vertical line.
From slope to equation
Once you have m, plug one of the points into y − y₁ = m(x − x₁) and rearrange to y = mx + b.
