Unit 4 Test Review

Front

Write the equation of a line with m = 3 that passes through (2, -1)

Back

y = 3x - 7

Front

Which of the following lines is PARALLEL to the graph of y = -6x + 3 and goes through the point (-1,4)?

Back

y = -6x - 2

Front

What is the y-intercept of the line y = -3x + 1?

Back

-3

Front

What is the slope of the line that contains these two points? (1, 6) and (3, -4)?

Back

-5

Front

Use the graph to determine the equation of the line in slope-intercept form: y = -3x + 3

Back

y = -3x + 3

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

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

Back

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

Front

What is the slope-intercept form of a linear equation?

Back

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

Front

What is the significance of parallel lines in terms of slope?

Back

Parallel lines have the same slope but different y-intercepts.
