Answer:
y=-1/3
Step-by-step explanation:
first combine like terms:
5/y-3/y=-2-4
2/y=-6
now multiply y on both sides:
2=-6y
solve the equation
y=-1/3
Answer:
The equation of Line is y = - 8x + 7
Step-by-step explanation:
Given as :
The slop of line is - 8
And The y intercept is 7
As the equation of line is y = mx + c
For y intercept , x = 0
So, With y intercept and slop ,
7 = (-8)× (0)+ c
Or, c = 7
So the equation of line is
y = mx + c
I.e y = ( - 8 ) x + 7
Hence The equation of Line is y = - 8x + 7 Answer
