Question

Solve the following systems of equations using the graphing method.
What type of system is it? Name the solution if there is one.
2x-2y=8
x-y=4
show graph

Answer 1

here is my work
2x-2y=8
-2x -2x
-2y=-2x+8
/-2 /-2
y=x-4


x-y=4
add y:
x = y + 4
subtract 4:
x - 4 = y or y = x - 4

Answer 2

i need help with the graph. what should graph look like?

this web will help you graph anything and everything :)

Answer 14

What do you need help with spence? :d looks like you've figured it out for the most part.
You determined that they're both the same line,
one is just a multiple of the other,

which means that they share infinitely many points, every point as a solution.

Answer 15

i think it is consistent since they are the same answer?

Answer 16

or would that be infinite

Answer 17

@fateal
