Whats (7,-4) and (7,0) in finding the slope from points
1 answer:
To find the slope of any line with two points given there is a specific formula you need to follow. You can apply this formula to anything.
Δy
------ or delta y over delta x
Δx
Long story short, this means the difference of the y values over the difference of the x values. With these two points given, you can find the slope through this expression:
= no slope
be mindful that no slope and zero slope are completely different. no slope is when the denominator is zero, because it is impossible for a denominator to be zero and zero slope is when the numerator is zero. Hope this helps!

Step-by-step explanation:
We know that,
Where,
X = raw score = 84
μ = mean = 68
σ = standard deviation = 10
Putting the values,
The percent of his sales that were less than or equal to 84 inches, is
Therefore, the remaining 100-94.5=5.5% were more than 84 inches.
