Front

What is the slope of the line represented by the equation y = 4 - 6x?

Back

The slope is -6.

Front

What is the first step to solve for slope-intercept form in the equation -x + 4y = 11?

Back

Add x to both sides.

Front

Define corresponding angles in geometry.

Back

Corresponding angles are angles that are in the same position on different parallel lines cut by a transversal.

Front

Identify an example of corresponding angles from the following: ∠8 and ∠4, ∠5 and ∠7, ∠1 and ∠7, ∠3 and ∠5.

Back

∠8 and ∠4 are corresponding angles.

Front

What is the product of 9 and 28?

Back

The product is 9/28.

Front

How do you find the missing angle in a triangle if two angles are known?

Back

Subtract the sum of the known angles from 180°.

Front

What is the formula for slope in a linear equation?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

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 value of x if the missing angle in a triangle is 20°?

Back

x = 20°.
