Question 1189880: 1) is the equation of a line that is perpendicular to the line given by the equation y=2?
2)
which equation represents the line that is parallel to the line whose equation y=-3x-3
3)
what is the equation of a line that goes through the point (3,12) and is perpendicular to the line given by the equation Y=-1/3x-7
4)what is the equation of a line that is parallel to the line that goes through the point (2,0) and(-2,-8)

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

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
