Slope and Slope-Intercept Form

Front

What is the formula to calculate the slope (m) of a line given two points (x1, y1) and (x2, y2)?

Back

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

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

The line is vertical.

Front

In the slope-intercept form of a line, what does 'b' represent?

Back

The y-intercept of the line.

Front

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

Back

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

Front

Find the slope of the line that passes through the points (3, 7) and (5, 11).

Front

If a line has a slope of -3, what does this indicate about the direction of the line?

Back

The line decreases as it moves from left to right.

Front

What is the y-intercept of the line represented by the equation y = 6x - 4?

Back

-4

Front

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

Back
