The line equation in slope-intercept form is , where m is

the slope and b is the y-intercept.

First find the slope of the line.

(Substitute )

(Product of two same signs is positive)

(Add: 2 + 1 = 3)

(Add: 1 + 2 = 3)

(Divide: )

Next find the *y*-intercept value by replacing *m* with 1, *y* with and *x* with in

the equation .

(Multiply: )

(Add 2 to each side)

(Simplify)

(Add: )

Replace *m* with 1 and *b* with 1 in the slope-intercept form line equation .

(Simplify)

The slope-intercept form line equation is .
