Answer:
![y-5=\frac{3}{4}(x-6)](https://tex.z-dn.net/?f=y-5%3D%5Cfrac%7B3%7D%7B4%7D%28x-6%29)
Step-by-step explanation:
we know that
The equation of a line in point slope form is equal to
![y-y1=m(x-x1)](https://tex.z-dn.net/?f=y-y1%3Dm%28x-x1%29)
step 1
Find the slope m
we have the points
A(-2,-1),B(6,5)
The formula to calculate the slope between two points is equal to
substitute the values
simplify
step 2
Find the equation of the line
we have
![(x1,y1)=(6,5)](https://tex.z-dn.net/?f=%28x1%2Cy1%29%3D%286%2C5%29)
substitute
![y-y1=m(x-x1)](https://tex.z-dn.net/?f=y-y1%3Dm%28x-x1%29)
![y-5=\frac{3}{4}(x-6)](https://tex.z-dn.net/?f=y-5%3D%5Cfrac%7B3%7D%7B4%7D%28x-6%29)
