Question

free medal to who ever helps me with this problem
solve the system by graphing
-3x-y=-10
4x-4y=8
a. (-1,3)
b. (3,-1)
c. (1,3)
d. (3,1)

Answer 1

-3x-y=-10 ---> 3x+y=10--->y=-3x+10
4x-4y=8 ---> x-y=2 ---> -y=-x+2 ---> y=x-2

so you have 2 equations in the slope intercept form,
y=-3x+10 &
y=x-2

plug in numbers for x (at least) twice, to find (at least) 2 coordinates, connect the coordinates with a line.
Do this for each line.
The point on which the lines intersect is your solution.
(write it as an (x,y) coordinate.)

Answer 2

so what would be the answer
