Answer:
Step-by-step explanation:
Answer:
-1
Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1
cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1
Hope this helps :)
Yes it is.
For every value of 'x' you can name, the value of 'y' is 5 .
If you mark several of those points on a graph, you see that
they form a straight line, which is horizontal and crosses the
y-axis at the point where 'y' is 5.
If the equation were not a linear one, its graph wouldn't be a straight line.
Answer:
The equation of the required line is: 2x + y = 8
Step-by-step explanation:
When a point on the line and the slope of the line are given, we use the slope - one - point form to determine the equation of the line.
Say, is the point passing through the line and the slope of the line is say, . Then the equation would be:
Here and slope, .
Therefore, the equation of the line becomes:
Rearranging we get:
which is the required equation of the line.
