The slope-intercept form is

y

=

m

x

+

b

, where

m

is the slope and

b

is the y-intercept.

y

=

m

x

+

b

Find the values of

m

and

b

using the form

y

=

x

+

b

.

The slope of the line is the value of

m

, and the y-intercept is the value of

b

.

Slope:

Any line can be graphed using two points. Select two

x

values, and plug them into the equation to find the corresponding

y

values.
