<u><em>The question in English is</em></u>
we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?
we know that
The formula to calculate the slope between two points is equal to

step 1
Find the slope ab
we have
a = (12 ,21) and b =(17,23)
substitute


step 2
Find the slope ac
we have
a = (12 ,21) and c =(3,9)
substitute


simplify

step 3
Compare slopes ab and ac
The slopes are different
That means ----> is not possible that a single road allows to join these three points

In a function, you need to substitute your input value for x in order to get your output. For example, if you have the function f(x)=3x, and your input value is 3, you have to substitute in 3 for x. In this case, 3 x 3 is equal to 9, therefore, your output for 3 in this function is 9. Keep in mind that the output always changes between equations.
