Hi again Mr. Joseph!
Well, the correct answer is option D
-------------------------------------------------
We need to find the equation using two points.
But the trick is that you need to solve for y but not x
So let's solve for y
- x + y = 3
Add x to both sides (Why? because we don't want x, so we need to get it out)
-x + y + x = 3 + x
y = x + 3
That's the correct equation.
They gave us (1,4)(5,8)
Use the slope formula and slope intercept form.
Do you know what the formula is?
Well, it looks like this
y = mx +b
So yeah, when we do all of that, we ended up having -x + y =3
Once again,
The correct answer is D
Best of luck with your studies!
