They are the same because they both have 4 sides
I'm assuming each tickmark is 1/4 = 0.25
If that assumption is correct, then going one tickmark to the left of -3/4 lands you on -4/4 which simplifies to -1.
So -1 is one tickmark to the left of -3/4
Again, this all hinges on the assumption that each tickmark is 1/4 a unit away from its neighbor.
A) 51, assuming this is a *right* triangle:
38^2+34^2 = 50.99^2, rounding 51!!
(1,2)
The solution is where the lines intersect so you can see they intersect at (1,2)
