Find the slope of the line between the points (−6, 2) and (0, 4).

• undefined

• 1/3

• -1/6

• 1/7

What is the equation of the line that includes (0,8) and (2,6) ?

• y = x + 8

• y = -x + 8

• y = 2x + 8

• y = 2x + 6

Write the equation of the line in point-slope form that goes through the point (10,5) and has a slope of -3.

• y - 5 = -3(x - 10)

• y= -3x + 35

• y + 5= -3(x + 10)

• y= -3x - 35

A farmer sells carrots for $4 per pound and squash for $3 per pound. On Sunday, she sold a total of $32 in produce. Write an equation for the situation using "x" for carrots and "y" for squash.

• y= 3x +4

• 4x + 3y = 32

• y= 4x + 32

• 3x + 4y = 32

Rewrite the point-slope equation into slope- intercept form:

y + 2 = -3(x - 5)

• y = -3x + 17

• y = -3x + 13

• y = -3x - 13

• y = -3x - 17

Nancy went to the grocery story. On Monday she purchased 4 apples and 6 bananas for a total of $13. On Wednesday she purchased 3 apples and 7 bananas for a total of $13.50. Which system of equations represents the situation? Use "x" for apples and "y" for bananas.

• 4x + 6y = 3

  13.5x - 13y = 6

• x + y = 4

  x - y = 6

• 4x + 6y = 13

  3x + 7y = 13.5

• 4x - 6y = 13

  3x - 7y = 13.5

The talent show committee sold a total of 530 tickets in advance. Student tickets (S) cost $3 each and the adult tickets (A) cost $4 each. If the total receipts were $1740, which system could be used to find how many of each type of ticket were sold?

• S + A = 530

  3S + 4A = 1740

• S + A = 530

  4S + 3A = 1740

• S + A = 1740

  3S + 4A = 530

• S + A = 1740

  4S + 3A = 530

The solution to a system of equations is any ordered pair that makes both equations true.

• TRUE

• FALSE

^{What is the solution?} 

• 1
• -2
• (1, 2)
• (1, -1)
