TOPIC 2 TEST REVIEW ANALYZE AND SOLVE LINEAR EQUATIONS

Front

What is the equation that models the amount of money, y, pizzeria W makes by selling x pizzas?

Back

y = 15x

Front

How do you determine which pizzeria makes more money per pizza when given a linear equation and a graph?

Back

Compare the slopes of the equations; the one with the higher slope makes more money per pizza.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the equation for the total cost of parking in a garage that charges $6 plus $1.75 per hour?

Back

y = 1.75x + 6, where x is the number of hours parked.

Front

How many solutions does the equation 5x + 4 = 3x + 8 have?

Back

One solution.

Front

What does it mean if an equation has infinite solutions?

Back

It means that there are an infinite number of values for the variable that satisfy the equation.

Front

What is the cost equation for renting a bike that charges $3.50 per hour plus a $7.00 equipment fee?

Back

y = 3.50x + 7.00, where x is the number of hours rented.

Front

How can you find the slope of a linear equation from a word problem?

Back

Identify the rate of change described in the problem, which corresponds to the slope.

Front

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

Back

The y-intercept represents the starting value when the independent variable (x) is zero.

Front

How do you solve for x in the equation 3(10x + 2) = 30x + 6?

Back

Distribute and simplify to find that it has infinite solutions.
