1. is 2?

Math please.

The probability of guessing them all wrong would be (3/4)^5 = .24
You managed to get the all wrong
1. In the form y = mx + b
the yintercept is b
in the equation y = (2/3)x + 2, what do you see in place of the b ?
2. isn't (0,5) the yintercept ?
so b = 5
which equation has 1/2 in front of the x and a 5 instead of the b ?
3. I subbed (1,2) into your choice and it did not work, no point trying the 2nd point.
Look at the points, in each case the y is 1 more than the x
Look at y = x+1
To me that says, the y is 1 more than the x
4.
Again isn't (0,4) the yintercept?
So which equation has +4 at the end ?
5.
Only B and D are in slope  yintercept form, ruling out A and C
Which of B and D has a slope of 2 ?
Sub in (2,3) in your choice to make sure 
Math please.

1. +2
2. y = 1/2x + 5 .. I had 5
3. y = x + 1
4. y = 4x + 4.
5. y = 2x + 7
thanks !
