Which of the following ordered pairs is a solution to the equation 2x-7y=20 ?
a) (-2,3)
b) (-3,2)
c) (0,10)
d) (3,-2)

Substitute each coordinate into the equation.

(3,-2) is the solution

Step-by-step explanation:

2x-7y=20

To find the ordered pairs that is a solution to the equation, we plug in each ordered pair and check whether it satisfies the given equation

A) (-2,3)

2(-2) - 7(3)=20

-4 -21 = 20

-25 = 20  (Does not satisfies the given equation)

B) (-3,2)

2(-3) - 7(2)=20

-6 -14 = 20

-20 = 20  (Does not satisfies the given equation)

C) (0,10)

2(0) - 7(10)=20

0 -70 = 20

-70 = 20  (Does not satisfies the given equation)

D) (3,-2)

2(3) - 7(-2)=20

6 +14 = 20

20 = 20  ( satisfies the given equation)

the answer

b. they are parallel and will never intersect.

d. vertex
