Question

Write the equation of the line that passes through the points (3, 6) and (4, 10) using function notation:

A. F(x) = 4x - 6
B. F(x) = x + 4
C. Y = x + 4
D. Y = 4x - 6

Answer 1

I know it's not c and d but I don't know if it's a or b

Answer 2

plugin the points and see which option satisifes both the points

Answer 3

(3, 6)

plugin x = 3 in first option :
F(3) = 4*3 - 6 = 12 - 6 = 6

so (3, 6) is indeed on this line

similarly test the other point also

Answer 4

How would I do that? @ganeshie8

Answer 5

Or you can actually figure out the equation of a line containing those two points

Answer 6

So is it A @ganeshie8

Answer 7

how did you get A ?

Answer 8

So would it be b bc the question is asking for a function notation @ganeshie8

Answer 9

function notation is f(x)
so the last 2 choices are knocked out already.

Answer 10

I think @ganeshie8 wants you to show your work on you got A as the answer.
