for the 2nd equation, take out 5 as the common factor on the left hand side , and divide both sides by 5, can you show me what would you get?
would it have none?
if you take out the common factor
5(x-4y) = 63
then divide both sides by 5
5(x-4y) /5= 63/5
(x-4) = 63/5

so it would be infinite??
it would only have 1.Correct??
after that , rewrite the 2 equations
x-4y=13 => x-4y-13 =0
(x-4y) = 63/5 => x-4y -63/5 =0
So , you can see that they have the same slope, but different y-int
So they are //lines, like this
So how many intercept(s) can you see?
What i the answer??
sorry i won't give you the answer directly this time.. you should work it out yourself
have you ever seen 2 parallel lines having intercept(s) ?
