Answer:
first find the slope of the line
slope =y2 - y1 / x2 - x 1 = -7+3/1+7 = -4/8 = -1/2
the slope of a perpendicular line is the negative reciprocal.
slope of bisector = 2
the line will be of the form y = 2x + b where b is a constant.
the line will pass through point (-3,-5)
this is because that is the x is in the middle of the x coordinates and the y is in the middle of the y coordinates.
plugging in the point into the equation:
-5 = -6 + b
b = 1
therefore, the equation is y= 2x + 1
