Write an equation in slope-intercept form for the line that passes through (-5,3) and is perpendicular to the line described by y= 5x.

Question

parthkohli · Answer

Okay, so do you know what the slope of a line perpendicular to another is?

anonymous · Answer

uhuhuhuh no not really

anonymous · Answer

Perpendicular Means Product of their Slopes = -1 ie m1*m2 = -1

parthkohli · Answer

It's like the opposite of the reciprocal. Got it? 
So if the slope is 8, then the slope of the perpendicular line is:

1) first find the reciprocal.
1/8

2) then the opposite
-1/8

So, can you do what is shown in the above?

anonymous · Answer

y= 5x

y = mx + c

m = slope

So in  y= 5x

m = 5


5 * m2 = -1

m2 = -1/5

nw use point slope form

y-y1=m(x-x1)

using  (-5,3)  m = -1/5

parthkohli · Answer

Instead, do it for 5. What is the opposite-reciprocal of 5?
