Explain how to round a number to the nearest ten.

Hope this helps :)

Step-by-step explanation:

Say you want to round the number 5.43

you pay attention to the 3

if the number is 4 or lower, the number stays 5.4

but if the number is 5 or above, you round up so it would be 5.5

but since the number is 5.43 u just leave it as 5.4

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)
