Which line is perpendicular to the line y=-1/3x-2 and passes through point (1,4)
2 answers:
Answer:
Option 3) y = 3x+1
Step-by-step explanation:
<u><em>Given equation is:</em></u>
y = 
Perpendicular => <u><em>It will have a slope of negative reciprocal to this slope</em></u>
So the ⊥ line has a slope = m = 3
Now,
Point = (x,y) = (1,4)
So, x = 1, y = 4
<u><em>Putting this in slope intercept form to get b</em></u>
=> 
=> 4 = (3)(1) + b
=> b = 4-3
=> b = 1
<u><em>Now, Putting m and b in the slope intercept form to get the required equation:</em></u>
=> y = 3x+1
Answer:
<h2>
y=3x+1</h2>
Option C is the correct option.
Given that,

Which is in the standard form

where, m= slope
c=y- intercept

Slope of perpendicular lines is the product of slope is -1.

Then, y=3x+c------> equation (i)
(X,y)=(1,4) ---- given
c=4-3x
c=4-3(1)
c=4-3
c=1
Put this in equation (i) we get,
<h2>
y=3x+1</h2>
This is the required equation of the line.
Hope this helps...
