Answer:
see below
Step-by-step explanation:
Choose a couple of values for x. Figure out the corresponding values for y. Plot those points and draw a line through them.
Let's choose x=0 and x=4. Then the corresponding y-values are ...
y = 2·0 = 0 . . . . . point (x, y) = (0, 0)
y = 2·4 = 8 . . . . . point (x, y) = (4, 8)
These are graphed below.
( 4 / 5 )^-2 = ( 5 / 4 )^2 = 25 / 16 ;
If you add that together you get 28
100+ 100+ 100+ 9= 309
200+ 50 +50= 300
