Question

how will i set up 5y-15=5x to be able to graph it

Answer 1

Well, change its form to the following by dividing everything by 5.

\[y=x+3\]

now we know the slope in this instance is 1 and we can easy see that one point on the graph must be (0,3), which is the y-intercept. The x-intercept can also easily be found by plugging in 0 for y and solving for x. In this instance, the x-intercept is (-3,0). Now you have two points and can draw the line or extrapolate other points.
