Front

What does the y-intercept of a linear equation represent in a real-world context?

Back

The y-intercept represents the initial value of the dependent variable when the independent variable is zero.

Front

Given the equation y = 2x + 5, what does the y-intercept (5) indicate?

Back

It initially takes 5 minutes to get homework out and start working.

Front

What is the x-intercept of a linear equation?

Back

The x-intercept is the point where the line crosses the x-axis, meaning the value of y is zero.

Front

In the equation y = 8x + 25, what does the y-intercept (25) represent?

Back

The starting fee of $25 for creating the team's design.

Front

How do you find the x-intercept of the equation y = 3x - 6?

Back

Set y to 0 and solve for x: 0 = 3x - 6, so x = 2.

Front

What is the slope of the line represented by the equation y = 3/5x - 1?

Back

The slope is 3/5, indicating the line rises 3 units for every 5 units it runs.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

Write the equation of a line with a slope of -2 and a y-intercept of 4.

Back

y = -2x + 4.

Front

What does the term 'linear equation' mean?

Back

A linear equation is an equation that forms a straight line when graphed, typically in the form y = mx + b.

Front

What is the significance of the slope in a real-world context?

Back

The slope represents the rate of change between the dependent and independent variables.
