Front

How do you find the slope of a line that passes through two points (6,7) and (4,2)?

Back

Use the formula: slope = (y2 - y1) / (x2 - x1) = (2 - 7) / (4 - 6) = 5/2.

Front

How do you calculate the slope from the coordinates of two points?

Back

Subtract the y-coordinates and divide by the difference of the x-coordinates.

Front

What is the formula for the slope of a line?

Back

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

Front

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

Back

The line is decreasing from left to right.

Front

What does a slope of 0 indicate about a line?

Back
