<h2>
There are infinite solution of y.</h2>
Step-by-step explanation:
Given,
y =
- 10x + 25
To find, the total number of solutions = ?
∴ y =
- 10x + 25
⇒ y =
- 2(x)(5) + 
⇒ y = 
There are infinite solution of y.
Thus, there are infinite solution of y.
It is (1,15). I recommend using a website called desmos because it helps with graphing.
But what is the expression, you have to tell me so I can do it.
