Sophomores Final

Front

On what axis would I expect to find point F?

Back

y-axis

Front

Write the equation of the line with slope 4 through the point (-2, 5).

Back

y = 4x + 13

Front

What is the slope of line KH if H(-4, 2) and K(2, -2)? Remember to reduce!

Back

-\frac{2}{3}

Front

In the expression 3x + 7, what is the variable?

Back

x

Front

If \(m\angle5 = 63\degree\), find the measure of \(\angle3\).

Back

117\degree

Front

What is the definition of slope in a linear equation?

Back

Slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.

Front

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

Back

Use the formula: \(m = \frac{y2 - y1}{x2 - x1}\)

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.

Front

What does it mean for two angles to be complementary?

Back

Two angles are complementary if their measures add up to 90 degrees.

Front

What is the formula for the slope-intercept form of a line?

Back

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