Algebra 1 Review - Chapter's 5 & 6

Tell whether the given ordered pairs satisfy a linear function. Explain.

• Yes, a constant change of +1 for and and +1, +2, +3,... continues with y

• No, a constant change in x corresponds to different changes in y

• There is no solution to this data

• the answer is undefined since x repeats

Tell whether the given ordered pairs satisfy a linear function. Explain.

• Yes, a constant change of +2 for x corresponds with a constant change of y which is -3

• No, a constant change in x corresponds to different changes in y

• There is no solution to this data

• the answer is undefined since x repeats

Lily plans to volunteer at the tutoring center for 45 hours. She can tutor 3 hours per week. The function f (x) = 45 - 3x gives the number of hours she will have left to tutor after x weeks. Graph the function and find its intercepts. What does each intercept represent? Attach your graph and reasoning to this question.

Use intercepts to graph the line described by the equation:

2x - 3y = 6

Find the slope of each line. Then tell what the slope represents.

• m = 4.5

• m = 6.5

• m = 8.5

• m = 10.5

Find the slope of each line. Then tell what the slope represents.

• m = -12

• m = -24

• m = -4

• m = 0

Find the slope of each line. Then tell what the slope represents.

• m = 1

• m = -1

• m = -2

• m = 0

Write the equation 2x - 2y = 4 in slope-intercept form, and then graph. Attach your work

Write an equation in slope-intercept form for the line through (-1,1) and (0,3)

• y = -2x - 3

• y = 3x - 2

• y = 2x + 3

• y = 2x - 3
