Front

What is the linear regression equation for a restaurant selling pizza with a price of 1.5 per pizza and a starting price of 12?

Back

The linear regression equation is y = 1.5x + 12.

Front

Solve the equation: 16w - 10w + 13 = -5

Back

The solution is w = -3.

Front

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

Back

The slope is 2.

Front

Solve the linear inequality: x > 5

Back

The solution is x > 5.

Front

Define slope in the context of a linear equation.

Back

Slope is the measure of the steepness of a line, calculated as the change in y over the change in x.

Front

What is the formula for finding the slope between two points (x1, y1) and (x2, y2)?

Back

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

What is the difference between a linear equation and a linear inequality?

Back

A linear equation shows a relationship that is equal, while a linear inequality shows a range of values that satisfy the inequality.

Front

How do you graph a linear equation?

Back

To graph a linear equation, find the y-intercept, plot it, then use the slope to find another point.
