Unit 2 Linear Relationships Review

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line, indicating the rate of change of y with respect to x.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept, which is the point where the line crosses the y-axis.

Front

How do you determine if a relationship is proportional from a table of values?

Back

A relationship is proportional if the ratio of y to x is constant for all pairs of values.

Front

What is the slope of the line represented by the equation y = 2x + 2?

Back

The slope (m) is 2.

Front

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

Back

The y-intercept (b) is (0, 2).

Front

What is the slope of the line represented by the equation y = \frac{1}{2}x - 1?

Back

The slope is \frac{1}{2}.

Front

What is the y-intercept of the line represented by the equation y = \frac{1}{2}x - 1?

Back

The y-intercept is (0, -1).

Front

If a bike rents for $4 plus $1.50 per hour, what is the equation in slope-intercept form?

Back

The equation is y = 1.50x + 4.

Front

What does a positive slope indicate about a linear relationship?

Back

A positive slope indicates that as x increases, y also increases.
