Y = mx + c
this is the equation of line and here m is the slope
so, 2x-6y =12 can be changed into standard format
y = 2x/6 - 12/6
y=x/3 +(-2)
so, m = 1/3 , so slope will be 1/3
hope it helped :)
26ft(yd/3ft)
8yd+2yd/3
8yd+(2yd/3)(3ft/yd)
8yd+2ft
8yd 2ft
Try 9:2 and 3:1 but I'm not sure if that's right or not
