What is the equation of a line given two points?

Back

To find the equation of a line given two points (x1, y1) and (x2, y2), use the formula: y - y1 = m(x - x1), where m is the slope calculated as m = (y2 - y1) / (x2 - x1).

Front

How do you calculate the slope of a line?

Back

The slope (m) of a line is calculated using the formula: m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.

What is a deductible in insurance?

Back

A deductible is the amount of money that a policyholder must pay out-of-pocket before the insurance company pays for covered expenses.

Front

How do you calculate the remaining balance after a deductible is paid?

Back

To calculate the remaining balance after a deductible is paid, subtract the deductible from the total bill. For example, if the bill is $850 and the deductible is $500, the remaining balance is $850 - $500 = $350.

What are coordinates in a coordinate grid?

Back

Coordinates are pairs of numbers (x, y) that define the position of a point on a coordinate grid, where x represents the horizontal position and y represents the vertical position.

How do you find the average of a set of numbers?

Back

To find the average, sum all the numbers and then divide by the count of the numbers. For example, if Marissa earned $45,200 for 3 years and $55,400 for 5 years, the average is calculated as (3*45200 + 5*55400) / 8.

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x = 0 in the equation of the line.
