Let’s say you weren’t given the slope, just the y-intercept and another point. How could you write the equation of that line in slope intercept form

Step-by-step explanation: The great thing about the y-intercept is that it is a point, but it always has an x-coordinate of zero.

So when we are given two points, you can easily find the slope of the points by taking the second y coordinate minus the first y coordinate and dividing it by the second x coordinate minus the first x coordinate.

That value will give you your slope or your steepness of the line.

The y-intercept is easy since you're already given it so just add or subtract it from your slope to write the equation of the line.
