Find David's errors and describe them in the space below.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

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

the answer is 5/14.

hope this .
