(a)
slope of f(x):
We can select any two points to find slope
(0,-3) and (1,0)
now, we can use slope formula
now, we can plug values
slope of g(x):
we can compare it with slope intercept form of line
we get
so, we can see that slope of f(x) is 3 while slope of g(x) is 4
so, slope of g(x) is greater than slope of f(x)
(b)
y-intercept of f(x):
we know that y-intercept is value of y when x=0
we are given point (0,-3)
so, y-intercept is -3
y-intercept of g(x):
we know that y-intercept is value of y when x=0
so, we can plug x=0 and find y
so, y-intercept is -5
Since, -3 is greater than -5
Hence , y-intercept of f(x) has greater value.........Answer
