43. If 4x-3y=2 and 3x+By=7 are perpendicular lines, what is the value of B? 

45. The circle shown has the equation x2 +y= 25. Find the coordinate dog any point p on the circle (other than A or B); then show that line PA is perpendicular to line PB. 

42. If 3x + y = 2 and Ax - 3y = 10 are parallel lines, what is the value of A?
43. If 4x - 3y = 2 and 3x + By = 7 are perpendicular lines, what is the value of B?
44. Show that a line whose x-intercept is (a, 0) and whose y-intercept is (0, b) has
the equation + = 1, which is often called the intercept form of a line.
