I am assuming the problem is asking you to find an equation repersenting the situation.
In this case, realize that 150 will be a constant, and 60 will be attached to the 
variable, since the price of the textbooks changes based on how many textbooks there are.
Thus, the equation is:
Our answer is 60x + 150 = y.
Answer: x = 6
Step-by-step explanation:
Since we are given two points on the graph, we first have to find the slope by using the formula m = y2-y1/x2-x1, where m is the slope.
Since it doesn't matter which set of points is x1 and y1 and x2 and y2, we are going to make (6,2) x1 and y1 and (6,-5) x2 and y2. Plugging those numbers in, we get m = -5-2/6-6 = -7/0 = undefined. So, we have an undefined slope.
Since we know we have an undefined slope, we also know that the equation is going to graph to be a vertical line and an x= equation. So, if we just look at the x's, we can see that since they are both 6, that is what our vertical line is going to be.
So, our equation is x = 6
The answer in slope-intercept form would be:
y=1/3x-3
All real numbers or is it multiple choice
13.8900 this is the answer. it is like this because thousandth is.0000. it Cant be 13.0089 because you would change the number.
