Answer:
This equation is a line
Step-by-step explanation:
We can tell it's a line because both the x and y values are raised to the first power. In order for it to be any of the others, one or both of the variables would have to have a non-one exponent.
It is a line.
Since, the general equation of,
A line is ax + by = c
A circle is
An ellipse is
A parabola is or
A hyperbola is
Where, a, b and c are constants.
Here, the given equation is,
x + y = 5
Which is the type of ax + by = c
Hence, x + y = 5 is a line.
