The equation 3x+5y-30=0 is the general form (standard form). Rewrite the original equation in slope-intercept form which is y=mx+b.






y=-3/5 x + 30/5

y=-3/5 x+ 6

In the equation y=mx+b. The m represents the slope and the b represents the y-intercept. Therefore the slope m=-3/5 and the y-intercept is b=6.

Formula: y=mx + c

 m represents the gradient and c represents the y intercept


5y= -3x+30

y= -3/5x + 30/5

     -3/5x + 6

the gradient is -3/5 or -.60

y-intercept is 6

In general the slope and intercept of y=mx+b is

m is the slope and b is the y-intercept.




Y= ( -3/5)x+30/5

y= (-3/5)x + 6

The above equation the slope is m= (-3/5) and b=6 is y intercept
