Literal Equations Practice

Front

Solve for y: 4x + 3y = 9

Back

y = -4/3x + 3

Front

Solve for y: x + 2y = −8

Back

y = −1/2 x − 4

Front

Which is the BEST first step to solve the equation y = mx + b for x?

Back

Subtract b

Front

What is a literal equation?

Back

An equation that contains two or more variables.

Front

What does it mean to solve for a variable?

Back

To isolate the variable on one side of the equation.

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

How do you isolate y in the equation 3y = 12 - 2x?

Back

Divide both sides by 3: y = 4 - (2/3)x.

Front

What is the first step to solve the equation 5x + 2y = 10 for y?

Back

Subtract 5x from both sides: 2y = 10 - 5x.

Front

What is the y-intercept in the equation y = 2x + 3?

Back

The y-intercept is 3.

Front

How do you convert the equation y - 4 = 2(x + 1) into slope-intercept form?

Back

Distribute and simplify: y = 2x + 6.
