Question

solve each system by graphing. tell weather the system has one solution, infinitely many solution, or one solution

y = x - 1

y = -3x - 5

Answer 1

first graph

Answer 2

where they intersect is our solution

Answer 3

confirming we can do something like solving by multiplying
the 2nd equation by (-1) and then add the 2 equations together.


0= 4x+4
-4=4x
divide both sides by 4 getting x by itself
-1=x
plugging in
y=(-1)-1
y=-2
checking
y=-3(-1) -5
y=3-5
y=-2

Answer 4

so the answer is one solution @zpupster

Answer 5

where are u why u dont answer @zpupster
