Question 574651: determine the value of k so that the graph of the equation passes through the given point.
kx + 4y = 2; (-1,2)
3x - ky = 1; 93,40
kx - 2y = -10, (-2,5)
trying to help grand-daughter and its been a long time since I was in school. Thank you

You can put this solution on YOUR website!
kx + 4y = 2; (-1,2)
Solution:
k(-1)+4(2)=2
-k+8=2
-k=-6
Answer: highlight%28k=6%29
3x - ky = 1; 93,40
Solution:
I think the point is (3,4), you forgot to press the shift key.
3(3) - k(4) = 1
9-4k=1
-4k=-8
Answer: highlight%28k=2%29

kx - 2y = -10, (-2,5)
Solution:
k(-2)-2(5)=-10
-2k-10=-10
-2k=-10+10
-2k=0
Answer: highlight%28k=0%29
