Which statement best represents the equation of the line shown on the grid and its relationship to the x-axis?

• A

• B

• C

• D

Answer explanation

Look at what axis the graph is touching or crossing.

In this case it's touching the y so it should be y=

Now compare the linear graph and the x-axis.

Are they perpendicular or parallel?

Perpendicular lines cross and make 90 degree angles.

Parallel lines never touch and go the same direction (same slope).

Linear function k has a zero of 3 and a y-intercept of 6. Which graph best represents k?

• F

• G

• H

• J

Answer explanation

zero is the x-intercept,

where the graph crosses the x-axis.

y-intercept is where the graph crosses the y-axis.

Which statement best describes the y-intercept of the graph?

• F

• G

• H

• J

Answer explanation

y-intercept is the starting point. The initial value.

• A

• B

• C

• D
