Step-by-step explanation:
if you are given an equation of a form y=kx+b, k is gradient and b is y-intercept
in c you can write this equation as y=(2x/3)-2,so gradient = 2/3 and y-intercept =-2
in e:6y=2x+3
y=x/3+1/2,gradient = 1/3, y-intercept=1/2
Answer:

Step-by-step explanation:

Add the fractions since the denominators are the same.


Simplifying the fraction.


Mean because all of the data points are
fairly close and there aren't any outliers
(extreme values)
