The graph of 5x2y=10 intersects the xaxis and yaxis what are the order pairs for these two points of intersection?
A.(2,0) and (0,5)
B.(2,0) and (0,5)
C.(2,0) and (0,5)
D.(2,0) and (0,5)

to get the x intercepts and y intercepts ( or as you call it two points of intersection), set one variable to 0 and solve for the other. then set the other variable to 0 and sovle for the first.
so let x be 0 first. 5*0 2y = 10
so 2y = 10,
so y= 5. We write this as (0,5) since x goes first and y last.
doing this for the second scenario, we set y = 0. so,
5x  2*0 = 10
5x= 10
x=2. Thus, since x goes first, we find (2,0)
therefore, we get (2,0) and (0,5)
and which answer is that may i ask? it is B.

ty sooooo much
another question (sorry about all these just trying to get this done and learn it before tom.)
Jennie calculated the probabilities of various events involving a coin. What is the probability of a coin landing on heads at least twice when the coin is flipped three times
a. 1/8
b. 1/6
c. 1/4
d. 1/2
*i think it is d and if it is i need work for it* *no matter what i need work*
