Question

Choose the ordered pair (x,y) that is a solution of the equation.

-15x – 2y = 23

Answer 1

All you have to do is get the left side of the problem to equal 23

Answer 2

how

Answer 3

(-1 -4)

Answer 4

A.
(-3,11)




B.
(2,-9)




C.
(3,-11)




D.
(-2,9)

Answer 5

i posted them

Answer 6

Okay, so what is preventing you from substituting the values for each point into the equations to test them and see if they are true?

Answer 7

i don't know how to do this at all

Answer 8

I'm sorry to hear that.

Answer 9

All you do is take each point and substitute their values into the equation one at a time and simplify it to test whether or not the equation is true. For example, the first given point (x,y) = (3,11) means that x = 3, y = 11, therefore I substitute it into the given equation to get

-15(3) – 2(11) = 23

Then I simplify it. Both sides of the equal sign will have to be true in order for the ordered pair to be the "chosen one".

Answer 10

thanks! but i still don't know

Answer 11

All you ave to do is take an ordered pair and substitute the right number for y and the left number for x

Answer 12

So -15x really means -15 times 3
and -2y means -2 times 11. add the two numbers together and whichever set gives you 23 is the correct answer
