2. Graphs of Equations

Use a graphing calculator to solve each linear equation. 3(2x+1) - 2 (x-2) =5

In Exercises 67–72, use intercepts to graph each equation. 6x-3y+15=0

In Exercises 79–80, find the value of y if the line through the two given points is to have the indicated slope. (3, y) and (1, 4), m = −3

Retaining the Concepts. If f(x) = 4x^2 - 5x - 2, find [f(x + h) - f(x)]/h, h ≠ 0

Exercises 143–145 will help you prepare for the material covered in the next section. If (x1,y1) = (-3, 1) and (x2, y2) = (−2, 4), find (y2-y1)/(x2-x1)
