Slope Review

Front

If a graph of a function is parallel to the x-axis, what does it indicate about the slope?

Back

It has no slope.

How do you calculate the slope of a line that passes through two points (x1, y1) and (x2, y2)?

Back

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

Back

2.

Front

How would you write the equation of a line with a slope of 2/3 and a y-intercept of -3?

Back

y = 2/3x - 3.

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
