Answer:
![y=7x+1](https://tex.z-dn.net/?f=y%3D7x%2B1)
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope
b is the y-intercept
In this problem we have
![m=7](https://tex.z-dn.net/?f=m%3D7)
![point(1,8)](https://tex.z-dn.net/?f=point%281%2C8%29)
substitute and solve for b
![8=7(1)+b](https://tex.z-dn.net/?f=8%3D7%281%29%2Bb)
![8=7+b](https://tex.z-dn.net/?f=8%3D7%2Bb)
![b=8-7=1](https://tex.z-dn.net/?f=b%3D8-7%3D1)
The equation of the line is equal to
![y=7x+1](https://tex.z-dn.net/?f=y%3D7x%2B1)
I hope this helps!!!
