Equation of a line

Front

What is the slope in the equation y=mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What does the y-intercept represent in the equation y=mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

Write the equation of a line with slope 2 and y-intercept 3.

Back

y = 2x + 3

Front

Write the equation of a line with slope -1/2 and y-intercept 2.

Back

y = -1/2x + 2

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

Write the equation of a line with slope 0 and y-intercept -2.

Back

y = -2

Front

Write the equation of a line with slope -4 and y-intercept 0.

Back

y = -4x

Front

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

Back

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