1st Semester Final Exam 2023 Review

Front

What is the first step to solve for x in the equation y=mx+b?

Back

Subtract b from both sides of the equation.

Front

Write the rule for the linear function represented by the equation: f(x) = -3x - 1.

Back

The rule for the linear function is f(x) = -3x - 1.

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Use the formula: slope = (y2 - y1) / (x2 - x1).

Front

Calculate the slope of the line that passes through the points (3, 6) and (9, 1).

Back

The slope is -5/6.

Front

Who has the greater rate of change (slope) between Smith with 5/4 and Harmon with 7/2?

Back

Harmon has the greater rate of change with 7/2.

Front

Define the domain of a function.

Back

The domain is the set of all possible x-values (inputs) for the function.

Front

Given the function {(0,1), (1,-3), (2,-4), (-4,1)}, what is the domain?

Back

D: {0, 1, 2, -4}.

Front

What is the range of a function?

Back

The range is the set of all possible y-values (outputs) for the function.

Front

For the function f(x) = 2x + 3, what is the slope?

Back

The slope is 2.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.
