Step-by-step explanation:
we start first by finding the gradient of the line
change in y/change in x
7-(-1)/3-7=8/-4
=-2
then for perpendicular lines m1m2=-1
therefore to find the gradient of that line
-2m2=-1
therefore m2=2
so therefore
y-5/x-3=2
so y-5=2x-6
y-2x=-1
in the form y= mx +c
then y=2x-1
Answer:
D
Step-by-step explanation:
Because They Are Even Number And Even Numbers Lead To Right Angles
Answer:
24 different possible votes
Step-by-step explanation:
This is a permutation problem. There's a formula: P(n,r)=n!/(n-r)!
Where P is the number of permutations (combinations), n is the number of objects (4 bands, in this case) r is the number of objects taken at a time (1st fav, 2nd fav and 3rd fav=3)
P(4,3)=4!/(4-3)!=4!/1!= 24/1= 24 combinations
Answer:
0.2
Step-by-step explanation:
The slope of the line is 
.
What is Slope?
The slope of a line is how steep it is going from LEFT to RIGHT. Slope is the proportion of a line's ascent, or vertical change, to its run, or horizontal change. No matter which two spots you choose for the line's starting and ending points, the slope is always constant (it never changes).
Here given two point are ,
Now using slope formula,
=> slope m= 
=> slope m= 
=> slope m =
Therefore the slope of the line is .
