Matching Linear Functions in Different Representations

Which equation represents the graphed blue line?

• y = 2x -3

• y = 3x +2

• y = -½ x + 3

• y = ½ x +3

Which equation represents the line with the given slope and y intercept?

• y = 2x + 3

• y = 3x + 2

• y - 2 = 3x

• y = 2/3 x

Which equation represents the linear function in the table?

• y = 2 + 3x

• y = -3 + 1/2 x

• y = - 1/2 x + 3

• y = 2x - 3

Which linear equation matches the following situation:

My bank account started at $200, but everytime I go to McDonalds, I spent $10.

• y = -10x + 200

• y = -200x + 10

• y = 10x - 200

• y = 200x -10

Which equation represents the graph?

• y = 1/3 x - 2

• y - 2 = 3x

• y = 2x - 3

• y = 3x – 2

Match the equation with the table.

• y = -2 + 3x

• y = -3 + 2x

• y = 1/3 x -2

• y = 3x

What is the slope of the line that goes through points ( 1, 9) and (-3, 8)?

• - 1/4

• 4

• -4

• 1/4

What is the slope of the line that goes through points ( 1, -5) and (1, 7)?

• Undefined

• 0

• 1

• -1

Match the equation of a line with a slope of -7 and y-intercept of 0.

• y = 7x

• y = -7x

• y = -7

• y = 7

Match the equation of a line with a slope of 0 and y-intercept of -12.

• y = -12

• y = -12x

• 12 = y

• y = x - 12
