1) Perpendicular to </span>
In order for lines to be
perpendicular, their slopes must be
negative reciprocals.Example of slopes with negative reciprocals: 5 and
First,
rearrange the equation into
slope y-intercept form:
The
slope of the equation is: \frac{1}{5}
The
negative reciprocal formula:
Solve for the negative reciprocal:
Divide both sides by
The slope of the new line is:
-5
2) Passes through (-5,-2)
Create an equation with the slope discovered in slope y-intercept form.
Input the point the line passes through.
Solve for b (the y-intercept).
Multiply.
Add -25 to both sides.
The y-intercept is equal to
-27

Answer:
y=4.5x+40
16 pairs of shoes
Step-by-step explanation:
Let the target earnings be represented by y and the number of pairs of shoes that Roger sells be x hence
y=4.5x+40
The equation is therefore, y=4.5x+40.
To solve this equation, substitute the value of y with 112 hence
112=4.5x+40
4.5x=112-40=72
x=72/4.5=16
Therefore, Roger should sell 16 pairs of shoes to achieve his target earnings of $112
4/5x=7/5 you have to divide 7/5 by 4/5 which equals to 1.75/5 which is equal to x
