Answer:
( -4, 7 )
Step-by-step explanation:
The difference between (2,3) and (-1,5) is (-3,2)
Because (-3,2) is the length of half the line we need to add that figure to M to get point S
(-1,5) plus (-3,2) is (-4,7)
k = 2
subtract 9 from both sides and you have 3k=6
then divide by three on both sides to get 2
2x + 4 I would assume
3 + 1 = 4
(combining like terms)
