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

Given the points (2, 8) and (3, 12), write the equation of the line.

Back

y = 4x.

Front

What is the slope of the line that passes through the points (0, 5) and (7, 6)?

Back

The slope is 1/7.

Front

How do you write the equation of a line given a point and a slope?

Back

Use the point-slope form: y - y1 = m(x - x1), where (x1, y1) is the point and m is the slope.

Front

What is the y-intercept of the line y = 4x - 12?

Back

The y-intercept is -12.

Front

How do you solve the equation -3x - 32 = -2(5 - 4x)?

Back

The solution is x = -2.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.
