PLZ HELP!! Fill in the blanks to complete the steps for finding the equation of a perpendicular line.

The value of m to be substituted in y – y1 = m(x – x1) is the negative reciprocal of the slope of the given line.
Substitute this in .
Substitute the given , (x1, y1), in the point-slope form.
Isolate y by and to rewrite the equation in slope-intercept form: y = mx + b.

The value of m to be substituted in y – y1 = m(x – x1) is the negative reciprocal of the slope of the given line.

Substitute this in for m.

Substitute the given point, (x1, y1), in the point-slope form.

Isolate y by multiplying out m and subtracting y1 to rewrite the equation in slope-intercept form: y = mx + b.

It should be something like this, hope this helped you!

the solution is 12x-6y

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
