Answer:
The correct answer is b) x - y + 1 = 0
Step-by-step explanation:
In order to find this, start by finding the slope using the two points given.
m(slope) = (y2 - y1)/(x2 - x1)
m = (5 - 2)/(4 - 1)
m = 3/3
m = 1
Now that we have the slope, we can plug into point slope form along with either point. Then we can solve for 0 to see which equation is correct.
y - y1 = m(x - x1)
y - 2 = 1(x - 1)
y - 2 = x - 1
-x + y - 2 = -1
-x + y - 1 = 0
x - y + 1 = 0

Answer:
This a 45 degree angle
Step-by-step explanation:
Given:
In a triangle,
![a=7,b=24,c=25](https://tex.z-dn.net/?f=a%3D7%2Cb%3D24%2Cc%3D25)
To find:
Whether the given segments are the sides of a right triangle or not.
Solution:
In a right triangle the square of largest side is equal to the sum of squares of two smaller side.
(Pythagoras theorem)
Three sides are
. Here, 25 is the largest side.
![25^2=625](https://tex.z-dn.net/?f=25%5E2%3D625)
Now, the sum of squares of two smaller sides is:
![(7)^2+(24)^2=49+576](https://tex.z-dn.net/?f=%287%29%5E2%2B%2824%29%5E2%3D49%2B576)
![(7)^2+(24)^2=625](https://tex.z-dn.net/?f=%287%29%5E2%2B%2824%29%5E2%3D625)
![(7)^2+(24)^2=25^2](https://tex.z-dn.net/?f=%287%29%5E2%2B%2824%29%5E2%3D25%5E2)
Since the sum of squares of two smaller side is equal to the square of largest side, therefore the given segments are the sides of a right triangle.
