D
uses the the formula y=mx+b and m is the slope. b is the y intercept.
(x+1)-(-2x-5)
=x+1+2x+5
=3x+6
=3(x+2)
Answer:
Infinite Answers
Step-by-step explanation:
You subtract 3x from both side which leaves you with 3=3, which leaves you to conclude there are infinite answers to this equation.
Answer: f(2) is 3.
Step-by-step explanation:
f(2) just means "what is the vale of the function, f, when x = 2? Look for x=2 and read the y value where the line crosses x=2, in this case, the y value is 3. So f(2) = 3.

[One could also determine the equation for the line. Provided below.]
The slope is -(1/2) and the y-intercept is 4:
y = -(1/2)x + 4
For x=2,
y = -(1/2)*(2) + 4
y = 3
y(2) = 3
