2) Solve the system of linear equations using elimination by addition or subtraction.
Sy=x-1
12. – y=0
O (1,2)
0 (-1,2)
O (-1, - 2)
O (1, - 2)

the answer is -1,-2

Step-by-step explanation:you add y to 2x-y and x-1 to 0, getting 2x=x-1. You go on from there, and the answer is x=-1, y=-2. Hope that helped

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
