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 :

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

Answer:

8)61.5 9)42.1

Step-by-step explanation:

8)61.5

area of square 10×10=100

circle=pie r^2

3.5^2×pie

=38.5

100-38.5=61.5

9)14×14=196

14/2=7

7=radius

pie×7^2

=153.9/2(because circle is half)

=76.95

76.95×2

=153.9

=196-153.9

42.1
