How do you graph #y=5/2x-2# using intercepts?
We can find that the x-intercept is
Drawing a straight line through these two points creates a graph of the function.
The x-intercept is the point at which the function meets the x-axis, which is the line
If we substitute
So one point on the line is the point
The y-intercept, similarly, is the point at which the function meets the y-axis, which is the line
So the y-intercept is the point
Simply drawing a line through these two points will create a graph of the function, using intercepts.
