The old mean was 51 now the mean is 42.33... (round that to 42) 51 - 42 = 9
The slope is 0 in this case because you are not moving up or down to get to the next point.
Mark me as brainliest if I helped!
Hope I did:)
90 minus 32 is 58! You were off by two degrees:)
3/4 ( (-50+2)/5)
= 3/4 ( -48/5)
= 3/4 * -48/5
= -36/5
