4.) What does the slope represent in context of this problem? 5.) Suppose your family has a coupon for free parking. Now, how much would your family of 4 pay to enter the park?
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
A family decides to take a trip to Kings Dominion this summer. Kings Dominion charges a flat fee of $15 for parking, as well as $54 per person to enter the park.
Equation y=54x+15
1.) If you have a school group of 30 people, how much would it cost the whole group to go to Kings Dominion?
y=54x+15
put x=30
y=54 (30)+15
y=1620+15
y=1635
2.) Why are you only graphing in the first quadrant? Why don’t you see an entire coordinate plane?
We are only graphing in the first quadrant because we know that persons can't be negative and the cost also cant be negative.
i.e. x≥0,y≥0
3.) What does the y-intercept represent in this problem?
Parking
4.) What does the slope represent in context of this problem?
5.) Suppose your family has a coupon for free parking. Now, how much would your family of 4 pay to enter the park?
