Slope-Intercept Form

Front

What do the variables x and y represent in the equation y = mx + b?

Back

A point on the line.

Front

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

Back

The coefficient m represents the slope.

Front

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

Back

The y-intercept, where the line crosses the y-axis.

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = 1/2x + 3?

Back

1/2.

Front

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

Back

y = 2x - 1.

Front

Write the equation of the line with a slope of -3 and a y-intercept of 4.

Back

y = -3x + 4.

Front

What is the slope of the line represented by the equation y = -1/4x + 2?

Back

-1/4.

Front

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

Back

The line is horizontal.

Front

If a line has an undefined slope, what does that indicate about the line?

Back

The line is vertical.
