Colour in so that the ratio of blue squares to green squares is 2:3 , 15 squares in the box

15/5= 3

Blue Squares: 3*2= 6

Green Squares: 3*3= 9

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
