Answer:

Step-by-step explanation:
Given the equation

comparing the equation with the slope-intercept form
Here,
so the slope of the line is m = -2/5
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,
so the slope of the perpendicular line will be: 5/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:



subtract 8 from both sides


Given:
Two planks are each 1.5 m long.
One plank is 2.5m long.
To find:
The total length of all the three planks.
Solution:
Two planks are each 1.5 m long. So,
First plank = 1.5 m
Second plank = 1.5 m
One plank is 2.5m long. So,
Third plank = 2.5 m
Now, the total length of all the three planks is



Therefore, the total length of all the three planks is 5.5 m.
