I'm very positive this is right
on second thought...
Answer: Third option.
Step-by-step explanation:
By definition, the slope of a line can be calculated with the following formula:
![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)
Since you need to solve for
to find an equivalent expression, you can apply these steps:
1. You must multiply both sides of the equation by
:
![m(x_2-x_1})=(\frac{y_2-y_1}{x_2-x_1})(x_2-x_1})\\\\m(x_2-x_1})=y_2-y_1](https://tex.z-dn.net/?f=m%28x_2-x_1%7D%29%3D%28%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D%29%28x_2-x_1%7D%29%5C%5C%5C%5Cm%28x_2-x_1%7D%29%3Dy_2-y_1)
2. Finally, you must add
to both sides of the equation:
![m(x_2-x_1})+y_1=y_2-y_1+y_1\\\\y_2=m(x_2-x_1})+y_1](https://tex.z-dn.net/?f=m%28x_2-x_1%7D%29%2By_1%3Dy_2-y_1%2By_1%5C%5C%5C%5Cy_2%3Dm%28x_2-x_1%7D%29%2By_1)
Answer:
X= 17
Step-by-step explanation:
In the picture above , you see that
BAE =~ DAE
So , just substitute the equation of each other and solve for x.
That's it.
