Algebra Test Linear Equations 3

Question 1

What does the x-intercept of a line represent?

Accepted Answer

Where the line crosses the x-axis

Answer

The x-intercept is the point where the line intersects the x-axis, meaning y = 0.

Question 2

Solve: -3x = 12

Accepted Answer

x = -4

Answer

Divide both sides by -3 to get x = -4.

Question 3

Which equation is parallel to y = 5x + 2?

Accepted Answer

y = 5x - 7

Answer

Parallel lines have the same slope; y = 5x - 7 also has slope 5.

Question 4

Solve for x: x + 14 = 9

Accepted Answer

x = -5

Answer

Subtract 14 from both sides to get x = -5.

Question 5

A line passes through (0, 4) and (2, 0). What is its slope?

Accepted Answer

-2

Answer

Slope = (0 - 4)/(2 - 0) = -4/2 = -2.
