<PRE><B>Question 1189880</B>
1 and 2 are missing choices.
1 has to be x= some constant
2 has to be y=-3x+/- some constant not -3.
-
3. the perpendicular line has a negative reciprocal slope, which here would be +3
point slope formula y-y1=m(x-x1); m slope, (x1, y1) point
y-12=3(x-3)
y=3x+3
{{{graph(300,300,-10,10,-10,10,3x+3,-(1/3)x-7)}}}
-
4. The slope of that line mss -8/-4=2
point slope formula y-y1=m(x-x1); m slope, (x1, y1) point
y-0=2(x-2)
y=2x-4
