Practice Test Unit 1 Algebra II

Front

Solve the inequality: -2(x+6)≥-10

Back

x≤-1

Front

What is the slope-intercept form of a line?

Back

The slope-intercept form is given by the equation f(x) = mx + b, where m is the slope and b is the y-intercept.

Front

Select the equation that models the line shown on the graph in slope-intercept form: f(x) = -4/5 x + 7, f(x) = 4/5 x - 7, f(x) = 5/4 x + 9, f(x) = -5/4 x - 9

Back

f(x) = -4/5 x + 7

Front

Solve for x: 3(6x-2)-2(3x+5)=62

Back

x = 13/2

Front

What is the inverse function notation?

Back

The inverse function of f(x) is denoted as f^{-1}(x).

Front

Which value is closest to f^{-1}(4)? x = 1, x = -8, x = 2, x = 10

Back

x = -8

Front

Solve the equation: -7x-2=-5x+12

Back

x = -7

Front

What does it mean for a function to be linear?

Back

A function is linear if it can be represented by a straight line on a graph, typically in the form f(x) = mx + b.

Front

What is the process to solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation using inverse operations.

Front

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness of the line and the direction of the relationship between the variables.
