Question

DECIDE WHEATHER THE ORDER PAIR(-3,-5) IS A SOLITION OF THE EQUATION 7X-5Y=15

Answer 1

Answer:

Not a solution

Step-by-step explanation:

Hello!

We can determine if it's a solution by plugging in the x and y-values of the point into the equation. If both sides are equal to each other, then it is a solution.

-3 is the x-value and -5 is the y-value, since an ordered pari is written in the form of (x,y).

Evaluate

• 7x - 5y = 15
• 7(-3) - 5(-5) = 15
• -21 + 25 = 15
• 4 ≠ 15

Since both sides are not equal to each other, (-3,-5) is not a solution.

Answer 2

Answer:

(-3, -5) is not a solution of the equation 7x - 5y = 15

Step-by-step explanation:

1) Knowing that coordinates are given to us as (x, y), plug in the ordered pair into the equation. $7(-3)-5(-5)=15$

2) Do PEMDAS on the left side of the equation

1. $-21+25=15$
2. $4=15$
3. $4\neq 15$
