Best ResponseYou've already chosen the best response.1since you don't actually need to find the solution(s) I would just put both in slopeintercept form and compare slopes then intercepts if necessary what I mean is you can have the following possibilities: A) Different slopes means one solution B) Same slopes and same yintercept means infinite amount of solutions C) Same slopes and different yintercepts means no solution

Best ResponseYou've already chosen the best response.1so y=2x+5 is already in slopeintercept form

Best ResponseYou've already chosen the best response.1to get x2y=2 in slope intercept form we want to write in y=mx+b form that means we will need to subtract x on both sides then divide both sides by 2 x2y=2 subtract x on both sides 2y=x+2 divide both sides by 2 y=1/2*x1
