perpendicular 2x+y=4,(1,2)

perpendicular

2 x + y = 4, (1, 2)

y = \frac{1}{2} x + \frac{3}{2}

Solution steps

Find the line

y = mx + b

perpendicular to

2 x + y = 4

that passes through

(1, 2)

Find the slope of

2 x + y = 4 : m = - 2

Compute the slope of the perpendicular line:

m_{p} = \frac{1}{2}

Find the line with slope m=

\frac{1}{2}

and passing through

(1, 2) : y = \frac{1}{2} x + \frac{3}{2}

y = \frac{1}{2} x + \frac{3}{2}

What is the perpendicular 2x+y=4,(1,2) ?
The perpendicular 2x+y=4,(1,2) is y= 1/2 x+3/2
