Question 1

Which of the following represents a linear function?

Accepted Answer

y = 2x + 3

Answer

A linear function has the form y = mx + b; y = 2x + 3 fits this form with m = 2 and b = 3.

Question 2

What is the y-intercept of the equation y = 3x - 7?

Accepted Answer

-7

Answer

In slope-intercept form y = mx + b, the y-intercept is b, which equals -7.

Question 3

Solve for x: 2(x - 3) = 10.

Accepted Answer

8

Answer

Distributing gives 2x - 6 = 10; adding 6 gives 2x = 16; dividing by 2 gives x = 8.

Question 4

Which ordered pair is a solution to the system: y = x + 2 and y = -x + 6?

Accepted Answer

(2, 4)

Answer

For (2, 4): y = 2 + 2 = 4 and y = -2 + 6 = 4, so (2, 4) satisfies both equations.

Question 5

Factor the expression x² - 9.

Accepted Answer

(x + 3)(x - 3)

Answer

x² - 9 is a difference of squares: a² - b² = (a + b)(a - b), so x² - 9 = (x + 3)(x - 3).
