Math HELP! Solve Each System By Graphing?

I don't understand it. Here are the questions....


a)y= -1/3x-3


y= -7/6x-8





b)y= 9/8x+5


y= -4





c)y= 2x+3


y= -1





It's for grade 10 math. When I type 3/4(3 over 4) that is a fraction just to let you know. PLEASE HELP ME

Math HELP! Solve Each System By Graphing?
When you input your data into your calculator under "Y=", enter the following exactly:





A)


y=-(1/3)x-3


y=-(7/6)x-8





B)


y= -(9/8)x+5


y= -4





C)


y= 2x+3


y= -1





The 2nd equations for B and C are just points on the graph and will be dots.
