Answer with explanation:
To determine the Equation of line in Point slope form
1.Choose a point on the line, such as (2, 5)
2. Choose another point on the line, such as (1, 3).
3.Count units to determine the slope ratio. The line runs 1 unit to the right and rises 2 units up, so the slope is 2.
4.Substitute those values into the point-slope form.
![y-y_{1}=m(x-x_{1})](https://tex.z-dn.net/?f=y-y_%7B1%7D%3Dm%28x-x_%7B1%7D%29)
y-3=2(x-1)
Step 3 is incorrect because it shows an incorrect ratio for the slope.
To determine the slope we use the following formula
![m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D)
Instead of counting how many rights and how many ups.
