You don’t know the answer don’t say anything and if you do know please help me:) Which of the systems of equations has a solution of (-2,6)? A.
y= 2x + 10
y = 3x - 6
В.
y - 2x = 2
y + 2x = 10 C. x - y = 9
y = x + 9
D. x + 2y = 10
-4x - y = 2

i need a diagram

step-by-step explanation:

no

- (2, -7)

- lines r and s and lines t and u must be parallel

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
