The equation of the perpendicular line to the given line is: y = -5/4x - 30.
<h3>What is the Equation of Perpendicular Lines?</h3>
The slope values of two perpendicular lines are negative reciprocal of each other.
Given that the line is perpendicular to y = 4/5x+23, the slope of y = 4/5x+23 is 4/5. Negative reciprocal of 4/5 is -5/4.
Therefore, the line that is perpendicular to it would have a slope (m) of -5/4.
Plug in m = -5/4 and (x, y) = (-40, 20) into y = mx + b to find b:
20 = -5/4(-40) + b
20 = 50 + b
20 - 50 = b
b = -30
Substitute m = -5/4 and b = -30 into y = mx + b:
y = -5/4x - 30
The equation of the perpendicular line is: y = -5/4x - 30.

Answer:
probability of getting four head consecutively is 0.2
Step-by-step explanation:
in an experiment coin is flipped 4 times.
given, coin landed heads up more than two times
outcomes of coin landed heads up more than two times =
SAMPLE SPACE : [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]
chance of getting 4 heads = 1 (HHHH)
Probability = 
hence the probability of getting four head consecutively is 0.2
