Linear Functions Quiz

What is the slope-intercept form of a linear function?

• y = mx - b

• y = mx^2 + b

• y = mx + b

• y = ax + b

Write the equation of a line in slope-intercept form if the slope is 2 and the y-intercept is 3.

• y = 2x + 3

• y = 2x - 3

• y = 3x + 2

• y = 2x - 2

Convert the equation 3x - 2y = 6 into slope-intercept form.

• y = (3/2)x + 3

• y = (3/2)x - 3

• y = (3/2)x + 6

• y = (3/2)x - 6

What is the standard form of a linear function?

• Ax + By = C

• Ax + By = F

• Ax + By = E

• Ax + By = D

Write the equation of a line in standard form if the slope is -1/2 and the y-intercept is 4.

• y=2x+4

• y=1/2x+4

• y=-1x/2+4

• y=4x+2

How do you graph a linear function?

• Plot at least two points and connect them with a straight line.

• Plot one point and connect it with a curved line.

• Use a ruler to draw a wavy line.

• Draw a zigzag line without any points.
