Standard Form Linear Equations

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A and B are not both zero.

Front

Which of the following is in standard form? y=3x-5, 3x+16=5y, 2/3 x + 9/13 y = 21, 5x+7y=-12

Back

5x + 7y = -12

Front

How do you find the x-intercept of a linear equation?

Back

To find the x-intercept, set y = 0 and solve for x.
