y = m x + b
This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept.
In this case :
b = 6 / 7
m = - 5
y = m x + b
y = ( 6 / 7 ) x + ( - 5 )
y = ( 6 / 7 ) x - 5 Multiply both sides by 7
7 y = 6 x - 35 Subtract 6 x to both sides
7 y - 6 x = 6 x - 35 - 6x
7 y - 6 x = - 35 Multiply both sides by - 1
- 7 y + 6 x = 35
6 x - 7 y = 35
A line has a slope of 6/7 and a y-intercept of -5. Which of the following is the equation of the line?
7x - 6y = -35
7x - 6y = -5
6x - 7y = 35
6x - 7y = -35
I'm honestly not sure with this, I'm thinking that it's 7x - 6y = -5.. Not sure though.
Also, could you explain how you found your answer? This would help so much..

Correction:
In this case :
m = 6 / 7
b = - 5
In this case :
m = 6 / 7
b = - 5
