Linear Equations Test Review

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 slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) 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

If a line has a slope of 2/3, what does this mean?

Back

It means that for every 3 units moved horizontally to the right, the line moves 2 units up.

Front

How do you convert the equation 3x + y = 12 into slope-intercept form?

Back

Rearranging gives y = -3x + 12.

Front

What is the y-intercept in the equation y = 4x + 3?

Back

The y-intercept is 3.

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope is -2.

Front

How do you identify the slope from the equation y = mx + b?

Back

The slope is the coefficient of x, which is m.

Front

What is the slope of a line that passes through the points (1, 2) and (3, 6)?

Back

The slope is 2.
