This might be wrong but I got 120/1008
Answer:
both are -10
Step-by-step explanation:
#1
x1 y1 x2 y2
1.5 180 6 135
(Y2-Y1) (135)-(180)= -45 ΔY -45
(X2-X1) (6)-(1.5)= 4.5 ΔX 4.5
slope= -10
B= 195
Y =-10X +195
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#2
x1 y1 x2 y2
1 175 8 105
(Y2-Y1) (105)-(175)= -70 ΔY -70
(X2-X1) (8)-(1)= 7 ΔX 7
slope= -10
B= 185
Y =-10X +185
Let
. Then
. By convention, every non-zero integer
divides 0, so
.
Suppose this relation holds for
, i.e.
. We then hope to show it must also hold for
.
You have
We assumed that
, and it's clear that
because
is a multiple of 3. This means the remainder upon divides
must be 0, and therefore the relation holds for
. This proves the statement.
