Answer:
The first one
Step-by-step explanation:
Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.
y=3x+1
The mean would be np, which here would be (6)(0.36) = 2.16.
So 75 points is your 100%. You can do 60 over 75 is equal to X over 100. You divide your numerator(60) by your denominator(75) to get 85.7142857%, or to round to your nearest percent, your answer would be roughly 86%.
Use the slope-intercept form y = mx + b to find the slope m and y intercept 'b'
Y - Intercept: 5
(Slope:) -3/4
