Algebra 2 - Semester 1 Review

Front

What is the slope of a line that is perpendicular to a line with slope m = 5/8?

Back

-8/5

Front

Find the slope of the line represented by the equation: 3y + 2x = 6.

Back

m = -rac{2}{3}

Front

Which equation represents a line with a slope of one half and a y-intercept of two?

Back

y = rac{1}{2}x + 2

Front

Simplify the expression: -7x + 5 - 9x - 2 + 3y.

Back

-16x + 3y + 3

Front

Are the lines y = \frac{1}{2}x + 2 and y = \frac{1}{2}x - 4 parallel, perpendicular, or neither?

Back

Parallel

Front

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

Back

m = \frac{y2 - y1}{x2 - x1}

Front

What does it mean for two lines to be perpendicular?

Back

Two lines are perpendicular if the product of their slopes is -1.

Front

If a line has a slope of 3, what is the slope of a line that is parallel to it?

Back

3

Front

What is the y-intercept of the line represented by the equation y = 4x + 5?

Back

5

Front

How do you find the slope from the equation of a line in standard form Ax + By = C?

Back

Rearrange to slope-intercept form (y = mx + b) to find m.
