Unit 2A Midterm Review

Front

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

Back

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

Front

Find the midpoint of the line segment with endpoints (-3,-8) and (9,3).

Back

(3, -2.5)

Front

What is the distance formula between two points (x1, y1) and (x2, y2)?

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

Find the distance between the points (-4, -8) and (-4, 0).

Back

8

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

Write the slope-intercept form of the equation of a line with slope -1/2 and y-intercept 2.

Back

y = -1/2x + 2

Front

How do you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

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