My co-worker erich is very odd. he only likes numbers that are divisible by 5. how many different last digits are possible in numbers that erich likes?

Solution:

A number is divisible by 5 if and only if it ends in 0 or 5, so there are only 2 possible last digits.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
