Question

Determine the function that represents the relationship.

A. y= 8x
B. y= 8x+ 14
С. y = 14x + 14
D. y = 1/8x + 14

Answer 1

b because if we use slope formula y2-y1/x2-x1 we get 8 and they already gave us the yintercept as 14

Answer 2

Option B

Explanation:

To solve these kind of question we just simply keep on inserting the values of x and if we get the required value of y that is in the table that equation is our answer, For example lets take Option A,

y = 8x

If we insert x = 0 we get,

y = 8(0)

y=0

but in the table it says we get 14 so option A is incorrect

Like this we keep checking for more values and all the values of x satisfy our equation in Option B like this,

`y=8x+14\\y=8(0)+14\\y= 14\\\\y=8x+14\\y=8(1)+14\\y=8+14\\y=22\\\\y=8x+14\\y=8(2)+14\\y=16+14\\y=30\\`

and so on so Option B is the answer
