QSE#2 Review - Algebra

Front

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

Back

Subtract b from both sides to isolate mx.

Front

What is the domain of the graph represented by the inequality -7 ≤ x < 5?

Back

The domain is the set of all x-values that satisfy the inequality.

Front

Back

To graph, rearrange to slope-intercept form and plot the y-intercept and slope.

Front

How do you write the equation in slope-intercept form for the line that contains the points (3, -5) and (5, -1)?

Back

Calculate the slope (m) and use the point-slope form to find the equation.

Front

What is the equation that represents the table of values where y = 2x + 5?

Back

This equation shows a linear relationship between x and y.

Front

Define slope-intercept form of a linear equation.

Back

Front

What does the slope of a line represent?

Back

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

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

Front

What is the y-intercept of the line represented by the equation y = 2x - 11?

Back

The y-intercept is -11, which is the value of y when x = 0.

Front

What is the significance of the domain in a function?

Back

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