Answer:
the equation of the line is 7x + y = 0 .
Step-by-step explanation:
in the standard form of the line that is Ax +By = C we can write it in the form of
By = C - Ax
![y = \frac{-A}{B}x +\frac{C}{B}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B-A%7D%7BB%7Dx%20%2B%5Cfrac%7BC%7D%7BB%7D)
which is in the form of ![y = mx +c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2Bc)
where m is the slope of the line and c is y intercept made by the line.
comparing
and ![y = mx +c](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2Bc)
we get that
and ![\frac{-C}{B} = c](https://tex.z-dn.net/?f=%5Cfrac%7B-C%7D%7BB%7D%20%3D%20c)
since it is given that slope of the line is -7 therefore m = -7 and c = 0
therefore
and ![\frac{-C}{B} = 0](https://tex.z-dn.net/?f=%5Cfrac%7B-C%7D%7BB%7D%20%3D%200)
therefore C = 0 , A = 7 and B = 1
therefore the equation becomes 7x + y = 0
