For all linear functions
f(x)=mx+b
m = slope
b = y-intercept (i.e.value of f(0), or value of y when x=0)
We're given
f(x)=-2x+5 => slope = -2, y-intercept=5
Examine the graph of g(x),
we have two intercepts (0,4) and (2,0)
this means slope=(0-4)/(2-0)=-2
y-intercept = 4 (y-value of (0,4)
therefore the equation of g(x)
g(x)=-2x+4 => slope = -2, y-intercept = 4
Means
A. slope of f(x)=slope of g(x) =-2
B. y-intercept of f(x)=5 > y-intercept of g(x)=4

-- The question tells us that . . . f(x) = -2x + 5
-- The graph tells us that . . . . . g(x) = -2x + 4
The first choice is the correct statement. It says ...
-- Over the interval [2, 4], the average rate of change of f (that's -2) is
the same as the average rate of change of g (that's also -2).
-- The y-intercept of function f (that's 5) is greater than the y-intercept
of function g (that's 4).
