TNReady Algebra Review

Meg's teacher asked her to find the zero(s) of the equation below.  Meg decided to factor to find the zero(s). 
0= x²-4x +4

(x + ___) (x + ___)

• (x + -2)(x + 2)

• (x + -4)(x + 2)

• (x + -4)(x + 4)

• (x + -2)(x + -2)

Multiply the binomials.
(x + 5)(x + 3)

• x² + 8x + 15

• x² + 15x + 8

• 2x² + 8x + 8

• 2x² + 15x + 8

Use the quadratic formula to solve 2x² + 2x - 12?

• -2, 3

• 2, 3

• 2, -3

• -2, -3

What is the correct value that represents the line of best fit for the data?
y = ____x + 6

• 1.8

• -0.5

• 0.5

• -1.8

What is the slope of a line that passes through the points (2, 3) and (4, 7)?

• 1

• 2

Solve the equation for y
4x+2y=16

• y=4x+16

• y=-2x-8

• y=2x+8

• y=-2x+8

Find the slope of the line containing these two points:
(-5, 1) and (-6, -3)

• m = 4/11

• m = 1/4

• m = -2

• m = 4

Factor completely:
x² - 121

• (x + 11)(x - 11)

• (x + 11)(x +11)

• (x - 11)(x - 11)

• x(x - 121)

Which of the following solutions fits the graph shown?

• -7 > x > -0.5

• -7 < x < -0.5

• -7 < x > -0.5

• -7 > x < -0.5

What is the Domain?

• -3 < x ≤ 3

• -4 ≤ x < 5

• -4 ≤ y ≤ 5

• -3 < y ≤ 3
