Step-by-step explanation:

y = m x + b

Then we can read the slope right off the equation: it is the number

represented by m.

I'll help you get one into this form:

Start with -2x+8y-4

Then add 4 to both sides: -2x+8.

Then divide both sides by 4: y = 3/4 x + 6/4.

This means that the slope is 3/4.

Try the other one on your own and reduce the slope to the smallest

possible fraction.

Now, what does this mean? If the slopes are the same, it means the two

lines are parallel. If one slope is the negative reciprocal of the

other, then the two lines are perpendicular. To get the negative

reciprocal of a number, put one over the number and then make it

negative. So:

  if the number is      its negative reciprocal is

        2                        -1/2

       3/10                     -10/3

      -3/2                        2/3

So if the two lines had these respective slopes, they would be

perpendicular.

If the slopes are neither the same nor negative reciprocals, the lines

are neither parallel nor perpendicular.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

answer: i believe the answer is e
