Answer: B
Step-by-step explanation:
because in A it says 2=3 and 2=2 that is not a function each number has to have an outcome of one possible answer if that is true it is a function.
I think it's 1/2 because 5/10= 1/2
I hope this helps!
Answer:
15
Step-by-step explanation:
4 x __ = 12
the blank would be 3, once you did it on one side you have to do it on the other side too
5 x 3 = 15
Another way you can do it is by...
= 
solve for x (cross multiply)
Point-slope form of equation is: 
Step-by-step explanation:
Given points are:
(2,-8) and (1,7)
First of all we have to calculate the slope of the line
so,

Point-slope form is given by:

Putting the value of slope

We can put any one of two given points in the equation to find the final form of point-slope form
So
Putting (1,7) in the equation

Hence, point-slope form of equation is: 
Reducing and simplifying
