These are some of the ones I missed any help?
A line perpendicular to y=3x-2 passes through (0,6) what are the points of the line?
A scatter plot shows a positive correlation which line equation would best fit:
a. y=-5x+1
b. x=16
c. 2x+3y=6
d. y=2x-1

If a line is perpindicular to y=3x-2 it will have a slope of m=-1/3. You know that the equation of a line is y=mx+b. Therefore the equation of the unknown line is 6=(-1/3)(0)+b. Solving you find that b=6. The line is y=-1/3x+6.
A positive correlation means that the slope of the line is positive. Answer a doesn't have a positive slope. Answer b is just a straight line. The answer is either c or d. But my best guess is d.

The slopes of perpendicular lines are negative reciprocals.
The equation of the perpendicular line is:
y - 6 = (-1/3)(x - 0)
y - 6 = -x/3
y = -x/3 + 6
A scatter plot shows a positive correlation which line equation would best fit:
A positive correlation implies a line with a positive slope.
The only line that qualifies is d. The answer is d.

A line perpendicular to y = 3x - 2 passes through (0,6) what are the points of the line?
The perpendicular will have the slope -1/3, so
(y - 6)/(x - 0) = -1/3
3y - 18 = - x
Solving for the intersection,
9x - 6 - 18 = - x
10x = 24
x = 12/5
y = (36 - 24)/5 = 12/5

y=-1/3x-2
y-6=-1/3x
y=-1/3x+6
y=-6(-1/3x+6)
y=2x-1
The answer is d.
