Answer:

y intercept: 18

x intercept: -25

Step-by-step explanation:

to find the x intercept, substitute y as 0 and solve for x. To find the y intercept, substitute x for 0 and solve for y.

X intercept:

-3/5x + 5/6y = 15

-3/5x + 5/6(0) = 15

-3/5x = 15

-To get x by itself with the fraction, flip it and simplify-

(-5/3)(-3/5x) = 15(-5/3)

x = -75/3

x = -25

Y intercept:

-3/5x + 5/6y = 15

-3/5(0) + 5/6y = 15

5/6y = 15

Do the same method to get y by itself

(6/5)(5/6y) = 15(6/5)

y = 90/5

y = 18
