Best way to find the intercept of 15x-12y=60, or of any line for that matter, is to put it into slope intercept form y=mx+b, where m is the slope and b is the y intercept
to do this we will need some equation manipulation to get it = to y
15x-12y=60
(15x-12y)+12y=(60)+12y
15x=60+12y
(15x)-60=(60+12y)-60
15x-60=12y
(15x-60)/12=(12y)/12
(5/4)x-5=y
y=(5/4)x-5
so m = 5/4 and b = -5
Final answer:
The y-intercept is at (0,-5)

Answer:
Part A: 6250
Part B: No
Step-by-step explanation:
Part B: When Time is 2 Hours, the cost is $30.
30x3=90 < 100
So the unlimited weekly pass is not cheaper

Answer:
The original price of the pants was $30.
Step-by-step explanation:
Let x be equal to the original price of the pants.
Because the pants are 40% off, their final price was 60% of the original price. 60% as a decimal is 0.6. Using this information, we can set up the following equation and solve:
0.6x=18
Divide both sides by 0.6
0.6x/0.6=18/0.6
x=30
I hope this helps!
