MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question.

Provide an appropriate response.

1) What is the equation of a vertical line through (-2, 5)?

1)

A) x = -2

B) y = 5

C) x = 5

D) y = -2

2) What is the equation of a horizontal line through (0, -1)?

2)

A) y = 0

B) x = 0

C) y = -1

D) x = -1

3) Given two points (x 1 , y 1 ) and (x 2 , y 2 ), where x 1

x 2 , what is the formula for the slope of the

3)

line connecting the two points?

y 2 + y 1

y 2 - y 1

y 2 - y 1

x 2 - x 1

A) m =

B) m =

C) m =

D) m =

x 2 + x 1

x 2 - x 1

x 1 - x 2

y 2 - y 1

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

4) y = x

4)

y = -x

y = -5x

Graph the set of equations on the same grid. Compare the slopes, y-intercepts, and

their effects on the graphs.

5) Given the slopes of three lines, m 1 = 2, m 2 = 5, m 3 = -4, which line would you say is the

5)

steepest? Why?

A) The line with a slope of 5 is the steepest, because the absolute value of 5 is larger than the

absolute values of 2 and -4.

B) The line with a slope of -4 is the steepest, because the absolute value of -4 is more

negative than the absolute values of 2 and 5.

C) The line with a slope of -4 is the steepest, because -4 is more negative than 2 and 5.

D) The line with a slope of 2 is the steepest, because the absolute value of 2 is smaller than

the absolute values of 5 and -4.

6) What is the relationship between the slopes of two parallel lines?

6)

A) There is no general relationship, because the y-intercepts can be different.

B) One slope is the negative of the other.

C) They are equal.

D) One slope is the reciprocal of the other.

SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question.

7) y = -x

7)

y = -x + 5

y = -x - 5

Graph the set of equations on the same grid. Compare the slopes, y-intercepts, and

their effects on the graphs.
