The product of the slopes of two non vertical perpendicular lines is always .1 it is not possible for two perpendicular lines
to both have a positive slope because the product of two positives is positive. so for the product of the slopes to be 1, one
of the slopes must be positive and the other negative.

The equation of a circle is (x - 3)2 + (y - 7)2 = 25. determine the length of the radius. 4 25 12.5 5 write the standard equation of the circle with center (2, 3) and a diameter of 12. (x - 2)2 + (y - 3)2 = 36 (x + 2)2 + (y + 3)2 = 12 (x - 2)2 + (y - 3)2 = 6 (x - 3)2 + (y - 2)2 = 36 the equation of a circle is (x + 3)2 + (y + 7)2 = 25. where is (3, 4) located in relation to the circle? on the circle in the interior of the circle in the exterior of the circle at the center of the circle

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2
