1/17/17 8-8 Writing Linear Functions

I can write equations given the slope and y-intercept, a graph, a

table, or two points. I can use linear equations to solve problems.

EXAMPLE 1. Write an equation in slope-intercept form for each

line.

A) Slope = -¼; y-intercept = 7

B)

EXAMPLE 2. Write an equation for the line that passes through

the points in slope-intercept form, standard form, and point-slope

form.

A) (7,0) and (6,3) B) (4, -2) and (12, 4)

C)

EXAMPLE 3. The number of customers living within 5 miles of a

restaurant is 150. The number of customers decreases by 30 for
