Answer:
Equation of line is:
![y=-15x+22](https://tex.z-dn.net/?f=y%3D-15x%2B22)
Step-by-step explanation:
Given points:
(2,-8) and (1,7)
To write the equation in point slope form.
Solution:
In order to find the equation of line, we will find the slope of the line by slope formula.
The slope
of the line passing through points
and
is given as:
![m=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
Thus, slope of given line can be given as:
![m=\frac{7-(-8)}{1-2}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B7-%28-8%29%7D%7B1-2%7D)
![m=\frac{7+8}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B7%2B8%7D%7B-1%7D)
![m=\frac{15}{-1}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B15%7D%7B-1%7D)
∴ ![m=-15](https://tex.z-dn.net/?f=m%3D-15)
The point slope of the equation for line with slope
passing through point
is given as:
![y-y_1=m(x-x_1)](https://tex.z-dn.net/?f=y-y_1%3Dm%28x-x_1%29)
Using point (1,7) to find the equation of line.
![y-7=-15(x-1)](https://tex.z-dn.net/?f=y-7%3D-15%28x-1%29)
Using distribution.
![y-7=-15x+15](https://tex.z-dn.net/?f=y-7%3D-15x%2B15)
Adding 7 both sides.
![y-7+7=-15x+15+7](https://tex.z-dn.net/?f=y-7%2B7%3D-15x%2B15%2B7)
[Answer]
The third side of the triangle is 26.
Explanation:
Given:
Two sides of the isosceles triangle are 26 and 10.
To Find:
The possible value of the third side
Solution:
Definition of Isosceles triangle:
An isosceles triangle is a triangle with (at least) two equal sides. Isosceles triangle has both two equal sides and two equal angles.
We also know the property of the triangle that
Sum of two sides of triangle > third side of the triangle
Case1. When third side is 10
Thee third side can’t be equal to 10 because it does not follow the rule of triangle
10+10>26………which is not possible
So the third side of the isosceles triangle is 26.
