Algebra Test Linear Equations 2

Question 1

What is the equation of a line with slope 3 passing through (0, -1)?

Accepted Answer

y = 3x - 1

Answer

Using y = mx + b with m = 3 and b = -1 gives y = 3x - 1.

Question 2

Solve for y: 7y = 49

Accepted Answer

y = 7

Answer

Divide both sides by 7 to get y = 7.

Question 3

Which value of x makes x/3 = 5 true?

Accepted Answer

x = 15

Answer

Multiply both sides by 3 to get x = 15.

Question 4

What is the slope of a horizontal line?

Accepted Answer

0

Answer

A horizontal line has no rise for any run, so its slope is 0.

Question 5

Solve: 2(3x + 1) = 14

Accepted Answer

x = 2

Answer

Distribute to get 6x + 2 = 14, subtract 2 to get 6x = 12, then divide by 6 to get x = 2.
