- 20, because If you look at the picture , the lcd is 20. (Bad explanation)
Simple...
you have: (7,-7) and (6,-5)
Using
to find slope--->>>
=-2
m=-2
Using y=mx+b to find the equation of the line-->>(Use any of the coordinates)
(7,-7)
-7=-2(7)+b
-7=-14+b
-7=-14+b
+14 +14
7=b
y=-2x+7
Thus, your answer.
