Question

what is the solution of the following system of equations?

y = -2/3x
y = 1

a)(1,-2/3)
b)(-3/2,1)
c)(-2,3)
d)(1,-3)

Answer 1

You have already been told that y = 1.
You also know that x = -(3/2)y, so x = -3/2

(-3/2, 1) is a way of writing that x= -3/2 and y = 1

Therefore the answer is (b)
