Answer:
81
Step-by-step explanation:
trust me its correct
(x,y)
y does't change makes it easier
frm 7 to -2
-2-7=-9
distance is 9
3d - e = 7d + e = 5 ⇒ 3d - e = 5
7d + e = 5
3d - e = 5
7d + e = 5 +
-----------------------
10d / = 10
10d = 10
d = 10/10
d = 1
7d + e = 5
7×1 + e = 5
7 + e = 5
e = 5 - 7
e = -2
