(-2,1)=1
=2 (0, 2)
=3 (2, 3)
Another method for graphing lines when an equation is in slope-intercept form is as follows:
1. Plot the y-intercept on the coordinate plane; that's the point (0, b).
2. Use the slope to find another point (and repeat).
3. Draw a line through the points.
1. Plot the y-intercept
2. Use the slope to find another point (and repeat).
3. Draw a line through the points.
(0, b) = (0, 7)
From the intercept, move down 5 and right 4 (or up 5 and left 4).
From (-3, 2), move up 7 and right 3 -– or down 7 and left 3.
