Math 1650 Homework Solutions Jason Snyder, PhD. Page 2 of 9 11 14 Find an equation for line whose graph is sketched. 12) The line passes through the points (-2,0) and (0,4), thus its slope is given by ° = 4 0 0 ( 2) = 4 2 = 2. The slope-intercept form of the line is therefore given by ? = 2 ? + 4. 14) The line passes through the points (-3,0) and (0,-4), thus its slope is given by ° = 4 0 0 ( 3) = 4 3 . The slope-intercept form of the line is therefore given by ? = 4 3 ? − 4.
