Answer:

Linear

Step-by-step explanation:

This equation is a linear equation. When you graph this out, you will obtain a straight line as the equation.

Additionally, you can also tell that this is a linear equation since the highest degree is 1. If it were a quadratic equation for example, you would have x^2, or y^2, and the highest degree would be 2.

Let me know if this helps!

What is the solution to the following system of equations? x+y=5

marta [7]

Answer:

(3,2)

Step-by-step explanation:

Let's solve this via elimination method:

$\begin{cases} x+y=5\\x-y=1\end{cases}$

By subtracting equation 2 from equation one we obtain:

$\begin{cases} x+y=5\\-(x-y=1)\end{cases}\\\\0x+2y=4\\\\y=2$

Next we can use any equation either 1 or 2 to determine what x is, I'll use equation 1. Let y=2 and so:

$x+y=5\\\\x+2=5\\x=5-2\\\\x=3$

Therefore the solution for the system of equations is:

x=3 and y = 2 as an ordered pair we have (3,2)
