Substitute the first number in each coordinate in place of x and the second number in place of y.

E.g. for A,

5x + 2y = -1

5(2) + 2(-4) = -1

10 - 8 = -1

2 = -1 <----- not true

Do this with all the options. You should find that D fits :)

Unless you are specifically told otherwise,

points are always given in the format (x, y)

For example, choice A is (x, y) = (2, -4)

therefore, you can check if it "satisfies" the equation

by using x = 2 and y = -4

5(2) + 2(-4) = -1 ?

10 - 8 = -1 ?

false

therefore choice A is NOT a solution.

The equation 5x + 2y = -one million is the equation of a line written in widely used sort. there is not any answer: there are infinitely many factors that lie on the line. to be certain that there to be a answer, there needs to be a 2d line. the answer of the equipment is the element at which the two traces intersect (if there is unquestionably a answer to the equipment of equations).

D. (1, –3)

What you have are called "ordered pairs". They exist as (x,y). So for A) x=2 and y=-4. What you need to do now is plug in the values for A thru D and see if they make the eqn true.

for these you don't gave to know how to solve them if they are multiple choice just plug in x and why for x and y in the equation and one should give you -1

it is D i dont know to explian it but i just plug them in and A B and C didnt work so its D

and one quote "when in dought Carlie out" which means pick C

I think it's C..
