linear equations

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are integers and A ≥ 0.

Front

Write the equation of the line in standard form: y = -2x - 3

Back

-2x + y = -3

Front

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

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

Write the equation for the line with slope 4 and y-intercept 3 in slope-intercept form.

Back

y = 4x + 3

Front

Write an equation in slope-intercept form that has m = 5/4 through (-4, -3).

Back

y = 5/4x + 2

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

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

Back

m = (y2 - y1) / (x2 - x1).

Front

What is the y-intercept of a linear equation?

Back

The y-intercept is the value of y when x = 0.

Front

Convert the equation 3x + 2y = 6 to slope-intercept form.

Back

y = -3/2x + 3.

Front

What is the x-intercept of a linear equation?

Back

The x-intercept is the value of x when y = 0.
