2. Graphs of Equations

Write an equation (a) in standard form and (b) in slope-intercept form for each line described. through (4, -4), perpendicular to x=4

For each line described, write an equation in

(a)slope-intercept form, if possible, and

(b)standard form.

through $(-2,4)$ and $(1,3)$

For each line described, write an equation in

(a)slope-intercept form, if possible, and

(b)standard form.

through $(2,-10)$, perpendicular to a line with undefined slope.

For each line described, write an equation in

(a)slope-intercept form, if possible, and

(b)standard form.

through $(0,5)$, perpendicular to $8x+5y=3$

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

Use intercepts to graph each equation. 6x-3y+15=0

Retaining the Concepts. If f(x) = 4x² - 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)
