Front

Write the equation of the line through the points (4, 5) and (12, 9).

Back

y = 1/2x + 3

Front

Write the equation of the line with slope 4 through the point (−2, 5).

Front

Write an equation for the line shown by counting the slope and identifying the y-intercept.

Back

y = -1/2x + 2

Front

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

Back

slope

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

3/2

Front

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

Back

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

Front

What is the y-intercept of the line represented by the equation y = 3x + 4?

Back

Front

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

Back

The line is horizontal.

Front

What is the equation of a vertical line that passes through the point (5, 2)?

Back
