how do you go about doing these?? =/?

Question

i cant figure it out pls help. and if you think its bad to help someone with h.w. then just dont answer pls.
okay,
-graphically solve and check ..i knowhow to check but i cant solev it that way cuz i dont have a graphic cal.

1) y= X squared - 4x + 3
y= x-1
so its x-1= x squared -4x + 3
where go from there? how to graph??

2) xy = -6
x+3y = 3
huh? thus one you dont have to graph just algebra.

Answer 1

you can always use graph paper and plot the curve and line yourself.

x^2 - 4x + 3 = x - 1
x^2 - 5x +4 = 0
(x - 4)(x - 1) = 0
x = 4 or 1

y = -6/x
x - 18/x = 3
x^2 - 3x - 18 = 0
(x - 6)(x + 3) = 0
x = 6 or -3
