the slope is 4/545 and the intercept is 4/15415

Explanation:

First let's multiply and get the form y=mx+ny=mx+n where mm is the slope and nn is the intercept:

12x+36-15y-21=1112x+3615y21=11

15y=12x+36-21-1115y=12x+362111

15y=12x+415y=12x+4

y=cancel12^4/cancel15^5x+4/15

y=4/5x+4/15

Then the slope is 4/5 and the intercept is 4/15
