The empty jug weighs 0.75 lb
With the 3c, the total weighs 2.25 lb. That means:
3c + empty jug = 3c + 0.75 = 2.25
3c = 2.25 - 0.75
3c = 1.5
and 1c = 0.5 (so c is a constant -or the slope-)
Then the equation is:
y = 0.5x + 0.75
<span>3x + 5y = 2 can be solved for 5y and then for y: 5y = -3x + 2, and so
y = (-3/5)x + 2/5. Slope is -3/5 and y-intercept is (0, 2/5). If you want more info, please ask specifically for what you want.
