Qzz: Standard Form (Ax+By=C)

Front

What is the standard form of a linear equation?

Back

The standard form of a linear equation is written as Ax + By = C, where A, B, and C are integers, and A should be non-negative.

Front

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

Back

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

Front

What is the x-intercept of the equation 2x - 4y = 8?

Back

(4, 0)

Front

Which of the following is in standard form? y = 1/2x + 2, y - 3 = -5(x + 2), -7x + 2y = 9, 3x + 2 = y

Back

-7x + 2y = 9

Front

How do you solve for y in the equation -6x + 3y = 9?

Back

Rearranging gives y = 2x + 3.

Front

What is the solution for y in the equation -6x + 3y = 9?

Back

y = 2x + 3

Front

Front

What does it mean for a line to be vertical?

Back

A vertical line has an undefined slope and goes straight up and down.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

How do you convert the equation 3x + 2 = y into standard form?

Back

Rearranging gives -3x + y = 2.
