Help with linear equations/algebra homework

This guy has $10. he buys 3 milk and 2 bread he gets 5 cent change. when he buys 2 milk and 3 1 bread he gets $4.15 change. I need the equation and the solution.

x and y intercept when y=3x-6

x and y intercept when 4y-6x=12

need equation for (-5,3) (-3,-1)

Thank you so much for your help! :)

y = 3x - 6
x int -> 0 = 3x - 6
-> 6 = 3x
-> x = 2

y int -> y = 3(0) - 6
-> y = -6

4y - 6x = 12
4y = -6x + 12
y = (-3/2)x + 3

x int -> 0 = (-3/2)x + 3
-> 0 = -3x + 6
-> x = 2

y int -> y = (-3/2)(0) + 3
-> y = 3

equation for (-5, 3) (-3, -1)

slope =(-1-3)/(-3-(-5))
slope = -4 / 2
slope = -2

-1 = 2(-3) + b
b = 5

equation is y = -2x + 5
