Front

What is the slope in the equation y=2x + 3?

Back

The slope is 2.

Front

Which of these represents slope-intercept form?

Back

y = mx + b.

Front

Rewrite in slope-intercept form: 3x - y = 1

Back

y = 3x - 1.

Front

What letter represents the slope in the equation y = mx + b?

Back

m.

Front

The point where the line crosses the y-axis is called the:

Back

y-intercept.

Front

What is the y-intercept of the equation y = 4x + 5?

Back

The y-intercept is 5.

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does the 'b' represent in the slope-intercept form y = mx + b?

Back

The 'b' represents the y-intercept.

Front

If a line has a slope of 0, what does that indicate about the line?

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.
