You can look at the graph and see where the point crosses the y - axis for the y-int and for the x-int you look to see where the point crosses the x-axis. The coordinate with always have a coordinate of zero.
Set up ratio problem
.2 oz butter / (1/15) lb jelly = x / 1 lb jelly
Then cross multiply the stuff opposite each other in the fractions... set it up as a multiplication problem
.2 × 1 = (1/15) × x
.2 = (1/15)x
Multiply both sides of equation by 15 to clear out the (1/15) fraction and get x
x = 3
