Answer:
(A)
Slope for f(x) is 3
Slope for g(x) is 4
(B)
So, y-intercept for f(x) is greater
Step-by-step explanation:
(A)
Slope of f(x):
we can select any two points
(-1,-6)
so, x1=-1 and y1=-6
(0,-3)
so, x2=0 , y2=-3
now, we can use slope formula
now, we can plug values
Slope of g(x):
we can compare with
y=mx+b
so, m=4
so, slope is 4
(B)
For f(x):
we can select point as
x=0 , y=-3
so, y-intercept is -3
For g(x):
we can compare with
y=mx+b
where
b is y-intercept
we get
b=-5
we know that -3 is greater than -5
So, y-intercept for f(x) is greater
