Can you name some types of companies that might use linear graphs to assist with their companies success?

2. 7-3 Slope Intercept Form
Students will learn to write a linear equation in slope-intercept form given the slope and y intercept.

3. The graph
Y- intercept
X- intercept

4. slope Rise over run Rise Run Positive Slope M= 5 1 Negative Slope

5. Slope formula Y2-y1 X2-x1 (0, 2) (4, 0) 0-2 4-0 -2 = -1 4 2 M = -1/2
-2 = -1
M = -1/2
What is the slope of the blue line?
M= 2

6. Slope Intercept Form
Given the slope m and y-intercept b of a line, the slope intercept form of an equation of the line is y= mx + b.
Y intercept
(0, b)

7. Write an equation in slope intercept form of each line with the given slope and y intercept.
M= -4, b=5
Y= -4x + 5
M= 1/3, b= -6
Y= 1/3 x - 6
M = 0, b = 3
Y= 3

8. Your Turn
m= 2, b=1
M= -5/3, b=0
M=0, b= -8
Y= 2x + 1
Y= -5/3 x
Y= -8
