Find f(2) for the function f(x) = |3x |
f(x) = |3x|
f(2) = |3 * | = | | =
Problem 2: Fill in the boxes below to solve.
Find the slope of -7x + 2y = 8 using slope intercept form
-7x + 2y = 8
2y = 7x + 8 Add to both sides
y = (7/ ) x + 4 Divide both sides by
Is this equation now in slope intercept form?
The slope of the line is
Problem 3: Suppose you drive a car 392 miles on one tank of gas. The tank holds 14 gallons of gas. (Assume the car travels the same distance for each one gallon of gas)
The number of miles traveled varies directly with the number of gallons of gas you use.
Write an equation that relates miles traveled to gallons of gas used. (Use any variable you like in the equation.
How far can you drive with 3.7 gallons of gas? (Make sure to show the calculations you did to determine this answer)

Problem 2: Fill in the boxes below to solve.
Find the slope of -7x + 2y = 8 using slope intercept form
-7x + 2y = 8
2y = 7x + 8 Add 7x to both sides
y = (7/ 2 ) x + 4 Divide both sides by 2
Is this equation now in slope intercept form? Yes
The slope of the line is 7/2

392 miles /14 gals = 28 m/g or 28 mpg
x =gallons used miles travelled = 28x
Miles travelled = 28 (3.7) = ?
