Unit 2A Midterm Review

Front

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

Back

Distance = √((x2 - x1)² + (y2 - y1)²)

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x).

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 a slope of 3 that passes through the point (0, 9).

Back

y = 3x + 9

Front

What is the equation of a line with a zero slope that goes through the point (6, 7)?

Back

y = 7

Front

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

Back

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