Timmy writes the equation f(x) = x – 1. he then doubles both of the terms on the right side to create the equation g(x) = x – 2. how does the graph of g(x) compare to the graph of f(x)? the line of g(x) is steeper and has a higher y-intercept. the line of g(x) is less steep and has a lower y-intercept. the line of g(x) is steeper and has a lower y-intercept. the line of g(x) is less steep and has a higher y-intercept

We have 
f(x) = x – 1
and 
g(x) = 2x - 2,
because when you double both of the terms of x - 1, you have to multiply each of the terms by two
so
g(x)=2*[x-1]> g(x)=2x-2

How does the graph of g(x) compare to the graph of f(x)?
f(x)=x-1
slope m=1  and y-intercept is -1

g(x)=2x-2
slope m=2  and y-intercept is -2

so
a)  The line of g(x) is steeper 
because slope
2 > 1
b) g(x) has a lower y-intercept
because
-2 < -1

therefore

the answer is
The line of g(x) is steeper and has a lower y-intercept
