Determine which of these relations are transitive. The variables x, y, x', y represent integers A.x~y if and only if x +y is pos
itive. B. (x, y)~(x/.y/) if and only if x+yx+y C.x~y if and only if xy 2 0 D.x~y if and only if x + y is even. Ex~y if and only if xy is negative. Fx~y if and only if x-y is a multiple of 10.

Step 1: Find the slope:
This gives you , but we need to find b.
To find b, substitute in one (x,y) pair and it doesn't matter which one. I'll go with (4,-2):
Now take that b-value and plug in into the slope-intercept form:
It's always a good idea to toss in the other x-value from the other point, to make sure it checks out.
