Unit 6 Test Practice

Front

Write the equation in slope-intercept form: 5x - 2y = 12

Back

y = 5/2x - 6

Front

Write an equation of a line perpendicular to y = 2/7x - 5 through (2, -3)

Back

y = -7/2x + 4

Front

Which is correctly written in standard form of y=-6/7x+12?

Back

6x + 7y = 84

Front

What is the slope of the line y=3?

Back

zero

Front

From the equation y = 3x + 18, what is the value of the x-intercept?

Back

-6

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 over the change in x (rise/run).

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

How do you find the y-intercept from a linear equation?

Back

Set x = 0 in the equation and solve for y.

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

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.
