Question

Is -7,4 a solution to 4x+5y=-13

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}☂$

Let's evaluate the equation using the coordinates of point (-7 , 4) to check if it's a solution for the given function.

$\qquad \sf  \dashrightarrow \: 4x + 5y = - 13$

$\qquad \sf  \dashrightarrow \: 4( - 7) + 5(4) = - 13$

$\qquad \sf  \dashrightarrow \: - 28 + 20 = - 13$

$\qquad \sf  \dashrightarrow \: - 8 \not = - 13$

Therefore, we can conclude that it's not a solution for the given function ~

Answer 2

Answer:

No

Step-by-step explanation:

Given that:

-7, 4

 Thus,

4(-7) + 5(4)

-28 + 20 = -8

- 8 ≠ -13

Doesn't equal  x

Hence, Answer =   No -7,4 is not a solution to 4x+5y = -13
