What equation is perpendicular to y=2x-3 and<br> passes through (-1, 2)?

Wittaler [7]

Answer:

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

Step-by-step explanation:

Equation of the given line: $y=2x-3$

Slope of the line = $2$

Slope of the perpendicular line = $-\frac{1}{2}$

So the equation of the perpendicular line:

$y=-\frac{1}{2}x+c$

This passes through the point (-1,2).Substituting in the equation:

$2=-\frac{1}{2}*(-1)+c$

=> $c=2+\frac{1}{2}$

=> $c=\frac{5}{2}$

So the equation of the line :

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