Linear Equations Test

Front

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

Back

The slope-intercept form of a linear equation is given by the formula y = mx + b, where m is the slope and b is the y-intercept.

Front

Convert the equation -3x + 4y = 12 to slope-intercept form.

Back

y = \frac{3}{4}x + 3.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

Calculate the slope of the line passing through the points (-2, -9) and (7, -3).

Back

The slope is \frac{2}{3}.

Front

What is the relationship between the slopes of perpendicular lines?

Back

The slopes of perpendicular lines are negative reciprocals of each other.

Front

If a line has a slope of 0, what does it look like?

Back

A line with a slope of 0 is horizontal.

Front

What is the equation of a horizontal line that passes through the point (4, -4)?

Back

The equation is y = -4.

Front

Determine the slope of the line given by the equation x = -7.

Back

The slope is undefined.

Front
