Answer:
q=-1
Step-by-step explanation:
.8-.4q=.2q+1.4
-.2q -.2q
.8-.6q=1.4
-.8 -.8
-.6q= 0.6
/-.6 /-.6
q= -1
It’s f(0)=3 because f(0) just means y intercept which is 3
M=slope=(y2-y1)/(x2-x1)=(-6-1)/(8-8)=-7/0 which is technically undefined. This is just a vertical line namely:
x=8 (you can think of a vertical line as having infinite slope)
In this question, we given a piece-wise function, that has different definitions depending on the domain.
Evaluate the function at x = 0.
The exercise asks for us to evaluate the function at 
We have to look at the definition, and see which definition includes . The equal sign at is on the second definition, that is:
Thus, at , the value of the function is 1, and the correct answer is given by option A.

The slope of AB is also -5. This is because parallel lines have equal slopes.
