Question 184942This question is from textbook elementary and intermediate algebra
: In each case determine whether the lines are parallel, perpendicular, or neither.
1)y=3x+2
y=1/3x-4
2)Point-Slope form
Write equation in slope-intercept form
x-y=1
3)Find the equation of the line that goes through the given point and has the given slope. Write in slope-intercept form.
(4,6)1/2

Answer by swiemers(10)   (Show Source):
You can put this solution on YOUR website! 1. The lines are perpendicular, because the slope of two perpendicular lines is the negative reciprocal.
2. Slope intercept form is y=mx + b, so you need to solve for y. Therefore,
y=x - 1
3. To find the equation of a line using one set of points and the slope, use the following formula: y-y^1=m(x-x^1)
With this problem, that equation would become:
y - 6= 1/2(x - 4) which would become:
y - 6= 1/2x - 2 and then
y = 1/2x + 4
Hope this helps! Good luck! Sandy :-)
