By only inspecting the system of equations, describe the lines as being parallel, intersecting, or coinciding. How many solution
s exist for the system?
y = −
1
2
x + 6
y = −
1
2
x
1 answer:
Answer: they are parallel
no solutions are there
steps
since b(y) in both cases is -1 and a(x) is 1/2 and c(the constant value) varies. ie 6 and 1
so
a1/a2 = b1/b2 ¥ c1/c2
so according to the system of equations in this case lines are parallel and thus there are no solutions
