pls help! I need help with a and c I did b already!

Answer:
A= y= -2x+7.
B= y= -[tex]\frac{3}{2}[/tex]x+ 6
Step-by-step explanation:
The linear equation is y=mx+b
A= y= -2x+7.
-2 represents he slope and 7 represents the y intercept.
B= y= -[tex]\frac{3}{2}[/tex]x+ 6
-[tex]\frac{3}{2}[/tex] is the slop and 6 is the y intercept.
Hope this helps :)
