8th Grade Slope and Slope-Intercept Form

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

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

Back

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

Front

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis (x=0).

Front

If a line has a slope of 2/3, what does this mean?

Back

For every 3 units you move to the right, the line rises 2 units.

Front

What is the equation of a line with a slope of 1 and a y-intercept of 0?

Back

The equation is y = x.

Front

How do you convert the equation y = 2x + 3 to slope-intercept form?

Back

It is already in slope-intercept form: y = mx + b.
