Honors Algebra 1 Midterm Review

Front

Solve: |2x - 1| = 7

Back

x = -3 or x = 4

Front

What are the slopes of perpendicular lines?

Back

Opposite reciprocals.

Front

Solve: -8 < 2(x + 4) or -3x + 4 > x - 4

Back

x < -8 or x < 2

Front

What are the slopes of parallel lines?

Back

The same.

Front

Convert to slope-intercept form: y + 5 = -3(x - 6)

Back

y = -3x + 13

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed.

Front

What is the slope-intercept form of a line?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What does it mean for two lines to be parallel?

Back

They have the same slope and will never intersect.

Front

What does it mean for two lines to be perpendicular?

Back

Their slopes are opposite reciprocals.
