Question

Does the ordered pair (-5,3) satisfy the system of equation?

y=-2x-1

y=-3/5x

a) Yes, because the ordered pair (-5,3) satisfies both equations of the system.
b) No, because the ordered pair (-5,3) satisfies only the equation y=-2x-1
c) No, because the ordered pair (-5,3) satisfies only the equation y=-3/5x
d) No, because the ordered pair (-5,3) satisfies neither equation of the system

Answer 1

C

Explanation:

Substitute -5 for x and 3 for y

y = -2x - 1

3 = -2(-5) - 1

3 = 10 - 1

3 ≠ 9

(-5,3) Is not a solution for this equation.

y = -3/5 x

3 = -3/5(-5)

3 = 3

(-5,3) is a solution for this equation.
