What is the substitution method in solving systems of equations?

Back

The substitution method involves solving one equation for one variable and then substituting that expression into the other equation.

Front

What is the first step in using the substitution method for the equations 3x + y = 8 and y = 4x - 6?

Back

Substituting y from the second equation into the first: 3x + (4x - 6) = 8.

Front

What is the product of (m-8)(m-9)?

Back

m² - 17m + 72.

Front

What type of number is a fraction?

Back

A fraction is a rational number.

Front

Which of the following is a linear function: y = 2x + 4, y = 2x² + 4, y = 2x(4 - 3x), xy = 15?

Back

y = 2x + 4 is a linear function.

Front

If f(x) = 2x + 25, what is f(5)?

Back

f(5) = 35.

Front

What is a linear equation?

Back

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

Front

What does 'm' represent in the slope-intercept form of a linear equation?

Back

In the equation y = mx + b, 'm' represents the slope of the line.

Front

What does 'b' represent in the slope-intercept form of a linear equation?

Back

In the equation y = mx + b, 'b' represents the y-intercept of the line.

Front

How do you find the slope between two points (x1, y1) and (x2, y2)?

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).
