The equation of a line in point slope form =

To put

into function notation, we need to get y by its self.
Lets say we had a point (2,2) and a slope of 3. Ok, now that we have our point and slope, lets turn point slope form into function notation.





Change the y to f(x)

<-----Function notation.
Answer:

Step-by-step explanation:
To simplify a fraction, you need to find the GCF (Greatest Common Factor) of the numerator (top number) and denominator (bottom number).
Factors of 14:
1, 2, 7, 14
Factors of 40:
1, 2, 4, 5, 8, 10, 20, 40
As you can see, 2 is the GCF of 14 and 40. So, we now divide both numbers by 2.
14 ÷ 2 = 7
40 ÷ 2 = 20
Therefore,
in simplest form is 
Answer:
53
Step-by-step explanation:
If there were only sandwiches bought, there would be 15, if there were only salads bought there would be 20. There’s probably more than one possibility, but that’s the best I can do, considering how long it’s been since I’ve done this type of problem. I’m all the way to learning determinants, so I really have to think to remember these. Sorry in advance if this doesn’t help at all, I’m not the best at this, but I can still try.
