Answer:

5 7/20

Step-by-step explanation:

basically, you are going to want to turn these into improper fractions

7 3/4 = 28/4 + 3/4

        = 31/4  (no further simplification)

2 2/5 = 10/5 + 2/5

         = 12/5

now get common denominator to subtract

31/4 - 12/5

155/20 - 48/20 = 107/20

if you want this back into mixed fraction then convert

107/20 = 5 7/20

Graph the line giving one point and the slope. 2x-6y=12
koban [17]
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 :)
