Answer:

The equation of the line is

y =  -  \frac{1}{2} x +  \frac{5}{2}

Step-by-step explanation:

Equation of a line is

y = mx + c

Where m is the slope

c is the y intercept

y = 2x + 3

Comparing with the above formula

m is 2

Since the lines are perpendicular the slope of the other line is the negative inverse of the original line .

That's

m = - 1/2

Equation of the line using point (1,2) and slope - 1/2 is

y - 2 = -1/2(x - 1)

y - 2 = -1/2x + 1/2

y = -1/2x + 1/2 + 2

The final answer is

y =   - \frac{1}{2} x +  \frac{5}{2}

Hope this helps you.

It would be 2 root 2
bc it simplifies to root 2 and root 4
