Front

What is the equation for a linear function with an initial value of 150 and a slope of 40?

Back

y = 40x + 150

Front

Back

x = 3

Front

What is the initial value in the equation y = mx + b?

Back

The initial value is represented by b.

Front

What is the equation that represents a linear relationship with a slope of 5 and a y-intercept of 5?

Back

y = 5x + 5

Front

If a company spends $1500 per day and $8 per teddy bear, what is the equation to find the number of bears t they need to sell to cover costs?

Back

1500 + 8t = 12t

Front

Define 'slope' in the context of a linear equation.

Back

The slope is the rate of change of y with respect to x, often represented as m in the equation y = mx + b.

Front

What does the y-intercept represent in a linear equation?

Back

The y-intercept is the value of y when x = 0, represented by b in the equation y = mx + b.

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What does it mean for two equations to be equivalent?

Back

Two equations are equivalent if they have the same solution set.
