1. Linear Equations

2. y –y1 = m(x – x1) Find and label y = mx + b y – intercept form slope
Point -Slope Form Given: (x,y) and m
y - coordinate
slope
x - coordinate

3. Find and lable
y = mx + b
y –y1 = m(x – x1)

4. (x1 , y1 ) and (x2 , y2 )

5. Jessie’s bus ride to school is five minutes more than 2/3 the time of Robert’s bus ride. Which graph shows the possible times of Jessie’s and Robert’s bus rides?

6. Jessie’s bus ride to school is five minutes more than 2/3 the time of Robert’s bus ride. Which graph shows the possible times of Jessie’s and Robert’s bus rides?

7. Suppose that the function f(x) = 2x + 12 represents the cost to rent x movies a month from an internet movie club. Makayla now has $10. How many more dollars does Makayla need to rent 7 movies next month?

8. f(7) = 2(7) $26 - $10 = $16
f(7) = f(7) = 26
Suppose that the function f(x) = 2x + 12 represents the cost to rent x movies a month from an internet movie club. Makayla now has $10. How many more dollars does Makayla need to rent 7 movies next month?

12. 10x + 5 = 7.5x + 25
2.5x = 20
x = 8

14. y – y1 = m(x – x1 )
y = 1.5(x – 1)
y = 1.5(x -1) + 12 OR
y = (x – 1)
