Learning Target Graph a line and write a linear equation using point-slope form and write a linear equation given two points.

In lesson 5-6 you saw that if you know the slope of a line and the y-intercept, you can graph the line. You can also graph a line if you know its slope and any point on the line.

Graph the line with the given slope that contains the given point.

Graph the line with the given slope that contains the given point.

Graph the line with the given slope that contains the given point.

Graph the line with slope –1 that contains (2, –2).

Write an equation in point-slope form for the line with the given slope that contains the given point. A. B. C.

Write an equation in point-slope form for the line with the given slope that contains the given point. a. b. slope = 0; (3, –4)

Write an equation in slope-intercept form for the line through the two points.
(2, –3) and (4, 1)

Write an equation in slope-intercept form for the line through the two points.

Write an equation in slope-intercept form for the line through the two points.
(0, 1) and (–2, 9)

Write an equation in slope-intercept form for the line through the two points.

The cost to stain a deck is a linear function of the deck’s area
The cost to stain a deck is a linear function of the deck’s area. The cost to stain 100, 250, 400 square feet are shown in the table. Write an equation in slope-intercept form that represents the function. Then find the cost to stain a deck whose area is 75 square feet.

HW pp /20-44,51   Find the cost to stain a deck whose area is 75 square feet.

Warm Up Find the slope of the line containing each pair of points.
1. (0, 2) and (3, 4) (–2, 8) and (4, 2) 3. (3, 3) and (12, –15) Write the following equations in slope-intercept form. 4. y – 5 = 3(x + 2) 5. 3x + 4y + 20 = 0 –1 –2 y = 3x + 11
