Question

antonio graphs these questions and finds that the lines intersect at a single point (-5,0.25)

Which statement is tru about the values x=-5 and y=0.25?

Serious answers please!

Answer 1

Given equations : Equation A:  4y -3x =16 and

Equation B: -x-8y =3.

We are given a point (-5,0.25) plugging it in first equation

4(0.25) -3(-5) =16

1+15 =16.

16 =16 : Satisfies first equation.

We are given a point (-5,0.25) plugging it in second equation.

-(-5)-8(0.25) =3.

5 - 2 = 3.

3=3.

Therefore, they are the only values that make both eqautions true.
