If the equation is 3x + 4y = -1

How would you find two points on that line to graph it?

Hi ZettaDigit,

Assign some arbitrary values for x and solve for y.

Or...find the x and y intercepts.

For instance, let x = 0

Then 3(0) + 4y = -1

0 + 4y = -1

y = -1/4

Point (0, -1/4)

This is actually the y-intercept.

To find the x-intercept, you would set y = 0 and solve for x.
