How do you find the y intercept of two points

Apr 28, 2022 · Best Answer. Say your two points are (-1,-2) and (3,4). Your y intercept is where the line your two points make crosses the y axis. You find this by taking one of your coordinates, (3,4) and you substitute it into the equation y = mx + c. The first number in your coordinate is your x value and the second is your y value. (x,y)

So your slope for this relationship is actually 0. Y is equal to 0x plus-- and then, you could just realize that the equation of this is just that y is always equal to 2. So it's 0x plus 2, which is the same thing as y is equal to 2. You could substitute back in. You could say OK, well, if y is equal to 0x plus b, that means that y is equal to b.
