How does one do the house method?​

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

i'm pretty sure the answer is a. decreases with increase in

c minus thirteen equals negative two. to find c add thirteen two both sides. this cancels out the thirteen and gives you eleven on the other side. this leaves you with c equals eleven.
