Point Slope & Slope Intercept Form

Front

What is the formula for slope?

Back

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

Front

What does 'rise' refer to in slope?

Back

Rise refers to the change in the y-coordinates (vertical change) between two points.

Front

What does 'run' refer to in slope?

Back

Run refers to the change in the x-coordinates (horizontal change) between two points.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

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

Back

Point-slope form: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

Front

Convert the point-slope form to slope-intercept form: y - 2 = 3(x - 1).

Back

y = 3x - 1.

Front

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

Back

Slope-intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the y-intercept from the slope-intercept form?

Back

The y-intercept (b) is the value of y when x = 0.

Front

If a line has a slope of 2, what does this indicate about the line?

Back

The line rises 2 units for every 1 unit it runs to the right.
