Answer:
1.5
Step-by-step explanation:
y2 - y1 ÷ x2 - x1
(3,4) (8, -3)
(x1,y1) (x2,y2)
Step 2 was his error.
The following problem is solved by Alan:

In solving for x, you have to cross multiply between the numbers.
In that case, step 2 would look like this:
(25)(x) = (8)(200)
NOT THIS:
(8)(x) = (25)(200)
Now continue all the way.
25x = 1600
x = 1600 ÷ 25
x = 64
