Algebra Test Linear Equations

Question 1

Solve for x: 3x + 7 = 22

Accepted Answer

x = 5

Answer

Subtract 7 from both sides to get 3x = 15, then divide by 3 to get x = 5.

Question 2

Solve for x: 2x - 4 = 10

Accepted Answer

x = 7

Answer

Add 4 to both sides to get 2x = 14, then divide by 2 to get x = 7.

Question 3

What is the slope of the line y = 4x - 3?

Accepted Answer

4

Answer

In slope-intercept form y = mx + b, the coefficient m = 4 is the slope.

Question 4

What is the y-intercept of the line y = -2x + 6?

Accepted Answer

6

Answer

The y-intercept is the constant term b = 6 in y = mx + b form.

Question 5

Solve for x: 5(x - 2) = 15

Accepted Answer

x = 5

Answer

Divide both sides by 5 to get x - 2 = 3, then add 2 to get x = 5.
