Please look in your text book for this problem Statement   The line equation in slope-intercept form is ,

where m is the slope and b is the y-intercept.

Calculate the slope,

m = (Substitute )

= (Divide: )­­

= (Product of two same signs is positive) The line crosses the y-axis at (0, 2). So the y-intercept is 2.

Substitute m = 3 and b = 2 in slope-intercept form line equation.  The slope-intercept form of the line equation is . TESTIMONIALS
