Question

Plot the X and Y intercepts to graph the equation y equals 1/3 x - 1​

Answer 1

see the graph below

Explanation:

If you add 1-y to both sides, the equation will be in intercept form:

x/3 - y = 1

This tells you the x-intercept is (3, 0) and the y-intercept is (0, -1).

The graph of the equation is the line through these points.

Comment on intercept form

When the equation is written as

x/a + y/b = 1

the x-intercept is "a", and the y-intercept is "b".

I find it convenient to use this form when I want to find both intercepts of the linear equation.
