An artist sells a painting for 20.50 but uses 5.75 worth of materials to make it. what will the artist total earnings be for selling the painting, after considering the cost of materials

$14.93

Step-by-step explanation:

An artist sells a painting for $20.50

The cost of the material that he uses to make it  = $5.57

His total earnings = selling cost - making cost

                              = 20.50 - 5.57

                              = $14.93

Total earning of the artist would be $14.93

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
