How do i find the y-intercept of an eqaution that passes throught two points

Answer 1

They way to find the y-intercept from two points is to first find the slope, which can be derived from the formula $m=\frac{y_2-y_1}{x_2-x_1}$.

Then, you can plug in one of the two points $(x_1,y_1)$ or $(x_2,y_2)$ into the formula y=mx+b to solve for b, which is your y-intercept.
