**Knights**, Thursday, February 21, 2013 at 5:56pmto 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.
