Algebra 1 Q1 2023 In-Class Review

Find the slope from the two points: (2, -8) and (-6, 32)

• m = 10

• m = -10

• m = 5

• m = -5

Given a line that passes through the ordered pairs (5, 0) and (-3, 32),

find the following:

Determine the slope of the line. Determine the zero.

• m = 4, zero = 5

• m = -4, zero = 5

• m = 4, zero = -3

• m = -4, zero = -3

Given g(x) = 8(6x); find g(-2)

• g(-2) = 32

• g(-2) = 14

• g(-2) = -16

• g(-2) = -96

What is the meaning of the y-intercept?

• Starting amount of water

• Starting Time

• Ending Time

• Amount of water lost per minute

What is the meaning of the x-intercept?

• Starting amount of water

• Starting Time

• Ending Time

• Amount of water lost per minute

Simplify the expression: (7mn – 12mp − 4np) + (5mn + 4mp − 6np)

• 12mn - 8mp - 10np

• 12mn - 8mp + 10np

• 2mn - 8mp - 10np

• 2mn - 8mp + 10np

Determine if the ordered pairs graphed below represent a function.

• Yes, because each x-value is paired with only one y-value.

• Yes, because each y-value is paired with only one x-value.

• No, because some x-values are paired with multiple y-values.

• No, because some y-values are paired with multiple x-values.

Determine if the ordered pairs graphed below represent a function. Why or why not?

• Yes, because each x-value is paired with only one y-value.

• Yes, because each y-value is paired with only one x-value.

• No, because some x-values are paired with multiple y-values.

• No, because some y-values are paired with multiple x-values.
