And there we have the line. Did this article help you? Using these two points, we can calculate the slope of this line. You can use either 4,5 or 8,7. The coordinates of the x -intercept are 3, 0. As you can see, once you have the slope, it doesn't matter which point you use in order to find the line equation. Did this summary help you? But you must use the same order for both the numerator and denominator!
Thinking about intercepts helps us graph linear equations. The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis.

The line crosses the axes at two points: If there is no y- intercept, the line has to be vertical, so the slope would be undefined and the equation. Solving for Slope-Intercept Form From Two Points No matter what you call it, this becomes the numerator or top number of the fraction that.

|Calculate the slope.
When calculating slope between two points, you can subtract the x and y coordinates from each other in either order, as long as you put the points in the same order for both rise and run.
