Write an equation for the perpendicular line to the line whose equation is 4y-5x=20 that contains the point (-2,-3)

The equation of a parallel line in point-slope form would be y = -4/5x - 23/5

Step-by-step explanation:

To find this, we must first find the slope of the original line. We can do this by solving for y.

4y - 5x = 20

4y = 5x + 20

y = 5/4x + 5

Now that we have the slope of the original line, we can find the slope of the new line. Perpendicular lines have opposite and reciprocal slopes, which means that while the original slope was 5/4, the new one will be -4/5. Now that we have that, we can use the point and slope and put them into the base form of point-slope form. Then we solve for y to get the final result.

y - y1 = m(x - x1)

y + 3 = -4/5(x + 2)

y + 3 = -4/5x - 8/5

y = -4/5x - 23/5

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
