Back

The y-intercept is 5.

Front

If the function rule is 4x, what is the output when the input is 5?

Back

The output is 20.

Front

If the function rule is 2x + 1, what is the output when the input is 2?

Back

The output is 5.

Front

Which equation matches the table of values where y increases by 1 for every increase of 1 in x?

Back

The equation is y = x + 5.

Front

What is the value of f(-5) if f(x) = 2x + 3?

Back

The value is -7.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

How do you calculate the output of a function given an input?

Back

Substitute the input value into the function rule and simplify.

Front

What is the general form of a linear equation?

Back

The general form is y = mx + b, where m is the slope and b is the y-intercept.
