Answer:
[tex]y=\dfrac{1}{2}x+2[/tex]
Step-by-step explanation:
y= - 2x + 1
Compare with y = mx + b
m = Slope = -2
Slope of the perpendicular line = -1/m = -1/-2 = 1/2
Point (2,3)
Equation : y -y1 =m(x -x1)
[tex]y - 3 = \dfrac{1}{2}*(x - 2)\\\\\\y-3=\dfrac{1}{2}*x - 2*\dfrac{1}{2}\\\\\\y -3=\dfrac{1}{2}x-1\\\\y =\dfrac{1}{2}x-1+3\\\\y=\dfrac{1}{2}x+2[/tex]
