e] i used the process of elimination- a] only works for the 1st pair, b] doesnt work for the 1st pair, c] and d] dont work for the 1st pair, so the only one left is e] !!!!!! hope that helps!!!! =D

In these kinds you need quick elimination, not fancy logic.

Test the equation at the point.

for x=0 what are your possible y-intercepts? You know the exact answer is y=3 from your first coordinate (0,3).

a) 3

b) 0

c) -1

d) -1

e) 3

That means only a) and e) are in the running.

For those two equations, what is the value of y at x=1? You know the exact value is y=5 from your second data point (1,5)

a) 3+3=6

e) 2+3=5

So the answer e fits your first two data points with not much more than a few seconds of thought.

It’s 2x + 3. You plug x into the equation and you should get the y value. i.e.: 2(0) +3=3, 2(1)+3=5, 2(4)+3=11

You apply the equation to each of the problems by putting numbers in for x and seeing if what the answer you come up with is te same as the answer under Y

For Example:

2 (0) + 3 = 3

2(1) + 3 = 5

2(4) + 3 = 11

This is the only equation listed that works for all 3 of the problems so it is the correct answer

y=2x+3

plug in the numbers

2*0is 0+3=3 so 0,3

2*1 is 2+3=5 so 1,5

2*4 is 8+3 =11 so 4,11

hope this helps
