Grant simplified the expression 1.5(-3.2+2.5) his work is shown below. Explain the error in grants work 1.5(-3.2+2.5)
=1.5× (-3.2)-1.5×(2.5)
=-4.8-3.75
=-8.55

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
