First: (the "m" variable represents the slope) substitute/replace the points in the slope formula which, is...
m = [second y - first y]/[second x - first x]
m = [- 4 - 5]/[- 3 - 0]
m = [- 9]/[- 3]
m = 9/3
m = 3
Sec: a line with a perpendicular slope...has the opposite slope (reciprocal)...which is, -1/3
perpendicular slope = -1/3

To find the slope of a perpendicular line, you just need to take the negative inverse of the slope of the original line. In this problem, the slope is calculated like so:
(-4 - 5) / (-3 - 0) = -9 / -3 = 3
therefore, the slope of a perpendicular line would equal
-1/3.

The slope of perpendicular lines are unfavorable reciprocals of one yet another. So, if line one has a slope of +a million/2, the line perpendicular to it could have a slope of -2/a million. to locate the slope of two factors, we use the formula (y2-y1)/(x2-x1). permit's make T(4,-3) factor one and U(5,0) factor 2: 0-(-3) ------- 5-4 we've got: +3/a million. The unfavorable reciprocal of which would be -a million/3, so B is your answer :) i'm hoping I helped! Take care and happy Easter!

slope of given line = (-4-5)/(-3-0) = 3
so required slope of perpendicular = -1/3

gradient of line joining (0,5) and (-3,-4) = 5-(-4)/0-(-3) = 3
since the product of the gradients of perpendicular lines is always -1,
gradient of perpendicular line = -1/3

m = (- 4 - 5) / (- 3 - 0)
m = (- 9) / (-3)
m = 3
Slope of perpendicular = (-1/3)
