The x is going by 15 and the y is going by 5
Answer:

Step-by-step explanation:
We are finding the equation of the line that coincide with line segment AB.
So, we can find the equation by using points A and B.

Slope of line (m) = 
Since slope = 0, therefore the line is parallel to x-axis.
The equation of line is given by 
where
is slope and
is y-intercept.
So equation of line AB:
where
and 



We need the square and the lengths of it to help you
For 3. It is the fourth choice. This is because angle DGF is vertical angle and thus equal to angle EGB. Then angle BGF is supplementary to this angle.
So your answer is EGB+BGF=180
For 4. It is the first choice of 62 ft. It is the midpoint so is half the total line segment.
