help Given the function f(x) = 4x + 10 and g(x), which function has a greater slope?


x g(x)
2 5
4 7
6 9
f(x) has a greater slope.
g(x) has a greater slope.
The slopes of f(x) and g(x) are the same.
The slope of g(x) is undefined.

well, clearly 4 > 1.

Answer:

f(x) has a greater slope.

Step-by-step explanation:

The slope of a function in the form of y=Mx+C is represented by the letter M, so the slope in the function F(x) =4.

Now when you have a function but you only have a table to evaluate it, to calculate the slope you have the next formula:

[tex]m=\frac{y^{2}- y^{1}}{x^{2} -x^{1} }[/tex]

You just have to pick two points from the table to use in the formula, we´ll use (4,7) as our point 1 and

(6,9) as our point 2.

This means that:

[tex]x^{1}=4[/tex] [tex]y^{1}=7[/tex]

[tex]x^{2}=6[/tex] [tex]y^{2}=9[/tex]

Now you just put it into the formula:

[tex]m=\frac{9-7}{6-4}[/tex]

[tex]m=\frac{2}{2}[/tex]

[tex]m=1[/tex]

Now that you have both slopes, you can see that the slope of g(x)=1 and the slope of f(x)=4, and you can see that f(x) has a greater slope thatn g(x).
