Find the point on the line y = 3x + 2 that is closest to the origin.
anzhelika [568]
1.
the slope of the line y=3x+2 is the coefficient of x, that is 3.

2.
the slope of any line perpendicular to the line y=3x+2, is m, such that:

3*m=-1

so m= \frac{-1}{3}

3. 
so any line with equation y=-1/3x+k is perpendicular to y=3x+2.

moreover, the line y=-1/3x (so k=0) is the line passing through the origin
(0, 0) and perpendicular to y=3x+2


4. This means that the closest point of y=3x+2 to the origin is the intersection point of lines y=3x+2 and y=-1/3x

5.
to find this point:

3x+2=(-1/3)x
x(3+1/3)=-2
x(9/3+1/3)=-2

x*10/3=-2

x= \frac{-2*3}{10} = \frac{-6}{10}=-0.6


thus y is :  (-1/3)(-6/10)=0.2



Answer: (-0.6, 0.2)
