Hello! Remember you have to write clear questions in order to get good and exact answers. Here, I'll assume the function as:

The y-intercept of a function is the point at which the graph of the function touches the y-axis. This occurs when we set
. In other words, we define the y-intercept (let's call it
as:

Setting
in our function we have:

So <em>in this context the y-intercept is -16</em>
10x+20y=150 is the equation I don't quite understand how she would have money left because she spend $150 for her t-shirts and jeans.
Hi there!
So, our two equations are:
2x + 3y = 20 and
-2x + y = 4
We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.
Divide 24 by 4, which is 6.
y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1
So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16.
The solution to the system is (1,6).
I hope I helped!
