Answer:
see the explanation
Step-by-step explanation:
we know that
The y-intercept is the value of the function y when the value of x is equal to zero
Part 1) we have

For x=0
substitute in the linear equation and solve for y


therefore
The y-intercept is the point (0,-6)
Part 2) Find the y-intercept of the function represented in the graph
Looking at the graph
For x=0
Find the value of y in the graph
The value of y is equal to y=1
therefore
The y-intercept is the point (0,1)
The equation showing the relationship between w and t is 
From the table, we have the following points:
(0,0) and (1,4)
Start by calculating the slope (m)

So, we have:

Simplify the numerator and the denominator

Divide 4 by 1

The equation is then calculated as:

This gives

Simplify

Hence, the equation is

Answer:
Line BD is Congruent to Line BD due to the Reflexive property. Angle Bad is congruent to angle BCD because of the third angle theorem therefore triangle ABD is congruent to triangle CBD because all angles and sides are congruent
I don't know if that will satisfy your teacher because some prefer different things but that leaves no ground to be inferred and explains everything word for word.
