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

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y-intercept )

y = 2x - 3 is in this form with slope m = 2

given a line with slope m , then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$

y = - $\frac{1}{2}$ x + b ← is the partial equation

too find b substitute (1, - 3) into the partial equation

- 3 = - $\frac{1}{2}$ + b ⇒ b = - 3 + $\frac{1}{2}$ = - $\frac{5}{2}$

y = - $\frac{1}{2}$ x - $\frac{5}{2}$ ← equation of line
