Which expression is equivalent to 4(5x+3y)

20x + 12y

Step-by-step explanation:

4 times 5x = 20x

4 times 3y= 12y

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
