Circle equation
(x-h)^2 + (y-k)^2 = r^2
where (h.k) is the center and r is the radius
(x -7)^2 + (y+10)^2 = 4
A) The probability that there are no boys in the car is given by:
The slope of line "v" is 
<h3><u>Solution:</u></h3>
Given that Line w and line v are perpendicular to each other
Also given that line w passes through the points ( -4, 8 ) and ( 12, -2 )
To find: slope of line v
Since line w and line v are perpendicular to each other, product of slopes of line w and line v are equal to -1
---- eqn 1
Let us first find slope of line w
<em><u>The slope "m" of a line is given as:</u></em>



Thus the slope of line "w" is 
Substituting the slope of w in eqn 1 we get,

Thus the slope of line "v" is
