The costs of a pack of noodles, a can of soda and a pack of bread buns are 120 Pesos, 45 Pesos, and 50 Pesos respectively. Brayden wants to buy x packs of noodles, y cans of soda, and z packs of bread buns.​

120x+45y+50z=C
This equation models this situation where C is the total cost

Hello there!
To find the x and y intercept points of the equation, plug in zero for the x and solve for y to find the y intercept, and vice versa.

To start, let's first start out by plugging in 0 for the x value and solve for y:
y=-1/3(0)+3
When you simplify this expression, you should get a result of y= 3.
This would mean that the point where your y intercept is at is at (0,3)

Now, let's solve for the x intercept by plugging 0 in for y and solving for x:
0=-1/3x+3
-3=-1/3x
-9=-x
x=9
Now that you have gotten x=3, you can conclude that the point of the x intercept is (9,0)

Hope this helps!
