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

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?

step-by-step explanation:

a) 0,0; 1,1; and 2,2

step-by-step explanation:

these have the exact same coordinates, thus they are the correct function.

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72
