Step-by-step explanation:
Given expression;
2x + y = -5;
The given equation must be written in a form where the slope is the negative inverse of the given one.
A line perpendicular to another will have a negative inverse slope.
2x + y = -5
Equation of a straight line is generally written as;
y = mx + c
y and x are the coordinates
m is the slope
c is y - intercept
2x + y = -5
y = -2x -5
The slope of the perpendicular = 
So,
the new line;
y = x -5
Any line with slope of will be perpendicular

ANSWER
or 
EXPLANATION
For 
We make y the subject to obtain,
We can easily graph this function, because we just have to transform the graph of 
by shifting the intercept up to 
.
As for the straight line, 
,
We find the intercepts as follows,
When 
.
When 
.
We plot the points 
and
.
We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be
