Unit 4 Review #3

Front

Write a linear equation with a slope of 1 and the y-intercept of -7.

Back

y = x - 7

Front

Write an equation that is parallel to y = -4x + 5 and passes through the point (-2, -1).

Back

y = -4x - 9

Front

What is the slope if the line is vertical?

Back

Undefined

Front

What is the slope if the line is horizontal?

Back

0

Front

Identify the slope and y-intercept of the equation x – 2y = 2.

Back

Slope: 1/2, Y-Intercept: -1

Front

What is the slope of a line that rises 3 units for every 2 units it runs?

Back

Slope = 3/2

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

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

Back

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

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope.

Front

What does it mean for two lines to be perpendicular?

Back

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