Question

The point (−1, 2) is a solution to which system of equations?

Responses

y=x−8
2x+y=7y is equal to x minus 8, , 2 x plus y is equal to 7,

y = x + 3
y = 3x + 5y = x + 3, , y = 3x + 5,

y = −12x + 6
y = 3x − 1y = −12x + 6 , , y = 3x − 1,

y = 23x + 6
3y + 6x − 18 = 0

Answer 1

Answer:(-1, 2) is a solution to the system of equations y = x + 3 and y = 3x + 5.

Explanation:

The point (-1, 2) is a solution to the system of equations:

y = x + 3

y = 3x + 5

To see this, we can substitute -1 for x and 2 for y in each equation and check whether the resulting equations are satisfied. When we do this, we find that:

2 = -1 + 3, which is true

2 = 3(-1) + 5, which is also true

Therefore, (-1, 2) is a solution to the system of equations y = x + 3 and y = 3x + 5.
