I noticed that this equation is in slope-intercept form (y = mx + b). M = the slope of the line, B = the y-intercept.
If the line is translated (fancy, fancy, talk for MOVED) up. The Y-intercept would change positive (because it is moved up) by four.
4 + 4 equals...well, 8.
Hope I could help you out! If my answer is incorrect, or I provided an answer you were not looking for, please let me know.

Answer:
I believe (D)
Step-by-step explanation:
-5x + 7 = -13
-7 -7
-5x = -20
-5/-5 -20÷-5
x=4
Answer:
x = 5 y =-2
Step-by-step explanation:
You can substitute the 4y in,
7x - (-3-x) = 43
7x + 3 + x = 43
8x + 3 = 43
8x = 40
x = 5
Then plug the x back into the equation,
4y = -3 - 5
4y = -8
y = -2
