Chapter 4 Practice Test

What is the slope-intercept form of the equation of a line with a slope of -8 and a y-intercept of 3?

Find the slope of the line through each pair of points (-13, -19) and (5, -18)?

• -18

• 18

Given the form y = mx + b, which variable represents the y-intercept?

• x

• b

• y

• m

Create a parallel equation to y = 2x - 6.

Answer explanation

To create a parallel equation, the slope remains the same. Therefore, the correct equation is y = 2x + 6, as it has the same slope of 2. The other answer choices do not have the same slope.

Write the slope-intercept form of the equation of each line.

• Parallel

• Perpendicular

• Neither

• Pie

Write the slope-intercept form of the equation of the line through the given points.

through: (2,5) and (0,-5)

• Neither

• Pie, don't choose this one.

• Perpendicular

• Parallel
