2. Graphs of Equations

For each line described, write an equation in(a)slope-intercept form, if possible, and(b)standard form. x - intercept (-3, 0), y-intercept (0, 5)

Find the slope of the line satisfying the given conditions. See Example 5. vertical, through (4, -7)

For each line, (a) find the slope and (b) sketch the graph. See Examples 6 and 7. y = 2x - 4

For each line, (a) find the slope and (b) sketch the graph. See Examples 6 and 7. 2y = -3x

For each line, (a) find the slope and (b) sketch the graph. See Examples 6 and 7. 4x + 3y = 12

Graph the line satisfying the given conditions.through (2, -4), m = 3/4

Graph the line passing through the given point and having the indicated slope. Plot twopoints on the line. See Example 7. through (-2, 8), m = 2/5

Graph the line satisfying the given conditions.through (0, 5), m= -2/3

Graph the line passing through the given point and having the indicated slope. Plot twopoints on the line. See Example 7. through (3, -4), m = - 1/3

Graph the line passing through the given point and having the indicated slope. Plot twopoints on the line. See Example 7. through ( - 1/2 , 4), m = 0

Graph the line passing through the given point and having the indicated slope. Plot twopoints on the line. See Example 7. through (9/4 , 2), undefined slope

Graph the line passing through the given point and having the indicated slope. Plot twopoints on the line. See Example 7. through (- 5/2 , 3), undefined slope

Find and interpret the average rate of change illustrated in each graph.
