Front

How do you calculate 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 = mx + b?

Back

The slope is m.

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line descends from left to right.

What is the slope of the line 2x + y = 7?

Back

-2

Front

What is the slope from the table if the change in y is 5 and the change in x is -2?

Front

If a line has a slope of 1, what does that mean about the angle it makes with the x-axis?

Back

It makes a 45-degree angle with the x-axis.
