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:
Below in bold.
Step-by-step explanation:
4x + y = 9
Let's put x = 0 then:
4(0) + y = 9
0 + y = 9
y = 9
So one. ordered pair that is a solution is (0, 9)
To get the answer, you will just use this operation: Division.
Let's divide it. 81 ÷ 13.5 = 6.
So, the answer is
Ben earns $6 per hour at the fun station.
Answer:
