Slope, Midpoint & Distance

Front

What is the formula to find the midpoint of a line segment with endpoints (x1, y1) and (x2, y2)?

Back

Midpoint = ((x1 + x2)/2, (y1 + y2)/2)

Front

Find the midpoint of the segment with endpoints (-7, -8) and (4, 7).

Back

(-1.5, -0.5)

Front

Front

What is the midpoint between (3, -1) and (7, -5)?

Back

(5, -3)

Front

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

Back

Slope = (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

If the slope of a line is positive, what does that indicate about the direction of the line?

Back

The line rises from left to right.
