Question

Which ordered pair is a solution to this equation?
-5x - 3y=25
a. -6,0
b. 0,-5
c. 0,-6
d -5,0

Answer 1

d

Answer 2

substitute and see which one of them solves the equation.
for example (-6,0) means you substitute x = -6 and y=0 in the equation
-5x-3y =25
LHS = -5(-6) - 3(0) = 30 which is not equal to the RHS (25).
so A is not the solution. try the rest and see which one solves it.

Answer 3

thanks d was right
