What is the y-intercept of the equation 5x + y = 5?

Back

(0, 5) - The y-intercept is the point where the line crosses the y-axis.

Front

Interpret the y-intercept in the equation y = 8x + 25 in the context of a T-shirt design company.

Back

The starting fee of $25 - This is the fixed cost before any t-shirts are printed.

Front

Solve the system of equations: y = 4x + 1 and 3x + 2y = 13.

Back

(1, 5) - This is the point where the two lines intersect.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.

Front

What is the slope of the line represented by the equation y = 2x + 3?

Back

2 - The slope is the coefficient of x in the equation.

Front

How do you find the x-intercept of the equation 5x + y = 5?

Back

Set y = 0 and solve for x: 5x = 5, so x = 1, giving the x-intercept (1, 0).

Front

What is the general form of a linear equation?

Front

What is the significance of the startup fee in the equation y = 8x + 25?

Back

It represents the fixed cost incurred before any t-shirts are printed.
