Unit 2 Mixed Review- Slope, Slope-intercept

Front

What is the slope formula?

Back

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

Front

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

Back

Subtract the y-coordinates and divide by the difference of the x-coordinates: m = (y2 - y1) / (x2 - x1)

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

In the slope-intercept form of a line, what does 'b' represent?

Back

In the equation y = mx + b, 'b' represents the y-intercept, where the line crosses the y-axis.

Front

What is the slope in the equation y = 4x - 2?

Back

The slope is 4.

Front

If a line has a slope of -3, what does this tell you about the line's direction?

Back

The line descends from left to right.

Front

What is the equation of a line with a slope of 2 that passes through the point (1, 3)?

Back

y = 2x + 1.
