Equations of Lines

Front

What does m represent in the formula y = mx + b?

Back

m represents the slope of the line.

Front

Write the equation of the line given the slope -3 and y-intercept -3.

Back

y = -3x - 3

Front

What is the y-intercept in the equation y = 2x - 3?

Back

The y-intercept is -3.

Front

Find the slope of the line that passes through the points (2, 3) and (4, 7).

Back

The slope is 2.

Front

Find the slope of the line that passes through the points (1, 2) and (3, -2).

Back

The slope is -2.

Front

What is the slope-intercept form of a line?

Back

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

Front

What does b represent in the formula y = mx + b?

Back

b represents the y-intercept of the line.

Front

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

Back

A slope of 0 indicates that the line is horizontal.

Front

If the slope of a line is undefined, what does that indicate about the line?

Back

An undefined slope indicates that the line is vertical.

Front

Write the equation of a line with a slope of 1 and passing through the point (0, 0).

Back

y = x.
