Linear Equations and Slope Practice Test

Front

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

Back

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

Front

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

Back

The slope is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What is the slope of the line represented by the equation y = -2x + 4?

Back

The slope of the line is -2.

Front

How do you convert the equation -4y = 8x - 16 into slope-intercept form?

Back

Divide by -4 to get y = -2x + 4.

Front

What is the y-intercept in the equation y = -1/3x - 6?

Back

The y-intercept is -6.

Front

What is the equation of a horizontal line?

Back

The equation of a horizontal line can be written as y = b, where b is a constant.

Front

How do you determine the equation of a line given two points?

Back

First, find the slope using the two points, then use the point-slope form to write the equation.

Front

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

Back

The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line.
