The weight of wrestlers on the team varies by 74 lbs is that mean, median, range or mode

Hmmm, I think it sound more like the average. So mean. I'm not 100% sure but it isn't the median or the mode.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
