Linear Equation

What characteristic defines a linear equation?

• A pattern of numbers increasing or decreasing by the same amount every step.

• A pattern of numbers that always doubles.

• A pattern of numbers that changes randomly.

• A pattern of numbers that only increases.

In the slope-intercept form of a linear equation, y = mx + b, what does the variable 'm' represent?

• The Y-intercept

• The slope

• The X-value

• The starting point

For the linear equation y = 2x + 1, what is the Y-intercept?

• 2

• x

A car's mileage starts at 27,000 miles and increases by 12,000 miles each year. In a linear equation representing this situation, what value would be the Y-intercept?

• 12,000

• 27,000

• 39,000

• 51,000

If a linear equation models the total mileage (y) of a car over 'x' years as y = 12,000x + 27,000, what does the coefficient 12,000 signify?

• The initial mileage of the car.

• The total mileage after one year.

• The number of miles driven per year.

• The number of years the car has been owned.
