FSA Practice Test (Algebra 1 End-of-Course)

Question 1

What is the slope of the line passing through the points (2, 5) and (4, 9)?

Accepted Answer

2

Answer

Slope = (9 - 5) / (4 - 2) = 4 / 2 = 2.

Question 2

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 3

Which set of ordered pairs represents a function?

Accepted Answer

{(1,2),(2,3),(3,4),(4,5)}

Answer

A function requires each x-value to map to exactly one y-value; only {(1,2),(2,3),(3,4),(4,5)} satisfies this.

Question 4

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

Accepted Answer

−4

Answer

In slope-intercept form y = mx + b, the y-intercept is b, which is −4.

Question 5

Simplify: 2³ × 2⁴

Accepted Answer

2⁷

Answer

When multiplying powers with the same base, add the exponents: 2³ × 2⁴ = 2^(3+4) = 2⁷.
