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

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

The graph Y- intercept X- intercept

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

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

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)

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

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