Question

x+y=10 what is the x and y intercept

Answer 1

to find the x intercept you would make y=0 then solve for x
to find the y intercept you would make x=0 then solve for y

Answer 2

thank youu :)

Answer 3

how would i do 9x=54-6y?

Answer 4

set it equal to 0 and solve for the variable..

Answer 5

9x=54-6y
9x=54-6(0)
9X=54-6
9X/9=48/9

Answer 6

5.3?

Answer 7

so set x to 0 and solve for y for the y intercept.. if its easier for you to see, you can rewrite the equation.

Answer 8

9x + 6y = 54

Answer 9

now.. substitute 0 in for x.. so 9(0) +6y = 54... so 6y = 54 .. so y = 54 / 6 ... thus y = 9.. so the y intercept is (0,9)

Answer 10

now take your same equation and plug in 0 for y making the equation 9x + 6(0) = 54. can you get it from here?

Answer 11

Ohh so you have to put it in standard form first?

Answer 12

you can do it without I believe.. but yes, its easier if you move all variable terms to one side and the constant terms to the other side, at least when doing the intercepts.

Answer 13

okay, thanks so much!!

Answer 14

no problem!! best of luck!! can you medal my answer if I helped you please? :)

Answer 15

yep ! :)
