Answer:
you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points
Answer: 31.57
Step-by-step explanation: If x is 37, that would mean 0.11 x 37 and that equals 4.07. Then you would add 27.50 and 4.07 and get 31.57.
Answer:
7
Step-by-step explanation:
71-16=56/8=7 number of points
Put the numbers in the given equation and solve for k.
... $11 = k·(8 €)
Divide by the coefficient of k:
... k = $11/(8 €) = 1.375 $/€
Then your equation is ...
... y = (1.375 $/€)x
_____
It is fairly common to leave the units out of such equations, assuming that everyone understands that x is in euros and y is in dollars and the conversion factor includes a unit change from euros to dollars. Thus, you might expect to see ...
... y = 1.375·x
