Please answer the following questions pertaining to the functions. Show your work! Given the equation 2x-3y=12
A) Determine if the solution(s) if the equation is paired with 3x+2y=31
B) Determine if the solution(s) if the equation is paired with 6x-9y=11
C) What types of slopes do parallel lines have?
A) 2x - 3y = 12 Multiply by 3
6x - 9y = 36
3x + 2y = 31 multiply by 2
6x + 4y = 62 Subtract first modified equation from second.
13y = 26
y = 2 Substitute that into original equation to find x.
B) Unless there are typos, this does not work.
6x - 9y = 36
6x - 9y = 11
