Front

What is an equivalent equation to 4x + 2y = 18?

Back

y = -2x + 9

Front

Solve for y: 5y + 34 = -2(-7y + 1)

Back

y = 4

Front

What does it mean if an equation has no solution?

Back

It means that there are no values for the variable that can satisfy the equation.

Front

What does it mean if an equation has infinite solutions?

Back

It means that any value for the variable will satisfy the equation.

Front

Solve for x: 7x - 3 = 7x + 5

Back

No Solution

Front

Solve for x: 7x - 3 = 5x + 7

Back

One solution: x = 5

Front

What is the first step in solving the equation 4x + 2y = 18 for y?

Back

Isolate y by subtracting 4x from both sides.

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 find the slope from an equation in standard form Ax + By = C?

Back

Rearrange to slope-intercept form (y = mx + b) to identify the slope m.
