PLEASE HELP Summarize the characteristics that the graphs y = 3x + 4, y = 2x + 4, y = -x +4, and y = -5x + 4 have in common.

-they are all straight lines

-they all cross the y-axis at (0,4)

Step-by-step explanation:

All these graphs intercept the y-axis at 4 OR

All these graphs b = 4

All these graphs have a slope or are non-vertical

Step-by-step explanation:

y = 3x + 4

y = 2x + 4

y = -x +4

y = -5x + 4

All these graphs intercept the y-axis at 4

slope intercept equation is y = mx + b, the line intercepts the y-axis at b

In addition, all these graphs have a slope or are non-vertical

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
