y = 5x + 3

To graph this line, we need to find two points of it on a graph and draw a straight edge using them. Two easy-to-find points are the y- and x-intercepts. The y-intercept of any linear function in the form

y = mx + b

is simply b. Is this case, b = 3. So a point must be (0,3). For the x-intercept, set y = 0 and solve for x:

0 = 5x + 3

-3 = 5x

-3/5 = x.

So a second point (-3/5,0).
