O(0,0) and A(a,b)
slope = (b - 0)/(a-0) = b/a
Answer is the first one
b/a
By the Pythagorean theorem,
The one in the bottoms left corner since no x values are repeated more than once
Answer:
2(x+3)
Step-by-step explanation:
X-y=1
x+y=3
You see the y's can cancel out. So add it together and you have:
2x=4
x=2
Now that you have x, plug it in to one of the equations to find y.
I will plug it into the first one.
(2)-y=1
-y=-1
y=1
