Question

Determine an equation for the line perpendicular to -3x+15y=13 passing through the points (0,3)

Answer 1

what is the slope for the perpendicular line?

first write your given into format y = mx + b so that you can easily see the slope of that line..

Answer 2

once you determine the perpendicular slope,
use point slope form to determine your new equation

y - y1 = m (x - x1)

given point is (x1, y1)

Answer 3

y=3/15x+13/15

Answer 4

great....you see the slope for the given line; what is the slope of perpendicular line?

Answer 5

y-3=3/15(x-0)

Answer 6

y=3/15x+3

Answer 7

slope of perpendicular line is negative recripocal

Answer 8

so the new slope is actually -15/3 or -5

Answer 9

parallel lines have the same slope

Answer 10

ooo i see

Answer 11

good :)
