Front

What is the y-intercept of the line represented by the equation y = 3/2x + 3?

Back

The y-intercept is (0, 3).

Front

How do you calculate the slope from a table of values?

Back

The slope is calculated as the change in y divided by the change in x (rise/run).

Front

What is the formula to find the slope between two points (x1, y1) and (x2, y2)?

Back

The formula is (y2 - y1) / (x2 - x1).

Front

Back

The slope is 1.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

If a line has a positive slope, what does that tell you about the direction of the line?

Back

A positive slope indicates that the line rises from left to right.

Front

If a line has a negative slope, what does that tell you about the direction of the line?

Back

A negative slope indicates that the line falls from left to right.

Front

What is the significance of the y-intercept in a linear equation?

Back

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