Question 1105877: Using the point slope linear equation, y + 4 = -4(x-2)....what is the equation in standard form of a perpendicular line that passes through (5,1)?
I have came up with y-1=(1/4)(x-5)
y-1=(1/4)x-5/4
y=(1/4)x-1/4
y=x/4-1/4
Is this the answer?

Question 1105895: I need some help on this please.
I know that "technically" tese do not "satisfy" the first set but it does for the second, however I feel like I am missing some steps

Is (-2,3) a solution for 3x+y =2 and x-2y=-8?
3(-2)+ 3 = 2
-6+3=-3 therefor no it is not
-2-(2)(3) = 8
(-2) - (6) = 8 Yes it is a solution for this one...
What am I missing?
