Step-by-step explanation:
Answer:
y = -0.9x+10.1
Step-by-step explanation:
The equation of the line is:
You have been asked to stimate m and b. To do so, first find the product between each pair of x and y and the value of x squared:
Then calculate the total sum of all columns:
m can be calculated following the next equation:
where n is the number of (x, y) couples (5 in our case).
Replacing the values calculated previously:
For b:
In the figure attached you can see the points given and the stimated line.

Answer: B) y = -5x+5</h3>
slope = -5, y intercept = 5
===========================================
Explanation:
The given equation has slope 1/5. We can see that by comparing it to y = mx+b, with m as the slope.
Flip the fraction and the sign to go from 1/5 to -5/1 = -5. The perpendicular slope is -5. We can stop here since only choice B has such a slope.
---------------
If you're curious about finding the y intercept, then you would use m = -5 along with (x,y) = (2,-5) to find the value of b
y = mx+b
-5 = -5(2)+b
-5 = -10+b
-5+10 = -10+b+10 ... adding 10 to both sides
5 = b
b = 5 is the y intercept
So we have y = mx+b update to y = -5x+5 as the perpendicular line.
