Find the slope
- 6x + 9y = 18
Transpose 6x
- 6x + 9y + 6x = 6x + 18
9y = 6x + 18
Divide both sides of the equation by 9
9y / 9 = 6x/9 + 18 / 9
y = 6/9x + 2
simplify
y = 2/3x + 2
The slope is 2/3
y intercept is 2

y intercept
x = 0
- 6x + 9y = 18
- 6(0) + 9y = 18
0 + 9y = 18
9y = 18
Divide both sides of the equation by 9
9y / 9 = 18 / 9
y = 18 / 9
y = 2
y intercept is 2

Do you mean the gradient by "slope"?. If so,
-6x+9y=18
9y = 6x+18
y = 2/3 x + 2
Since the formula of line graphs is y= (gradient)*x + (y-intercept), the gradient is 2/3 and the y-intercept is 2

9y = 6x + 18
y = (2/3)x + 2
Therefore slope is 2/3 and y-intercept is 2

9y = 6x + 18
y = (2/3) x + 2
slope = 2/3
y intercept is y = 2

first convert it into y intercept form
y=[6x+18]/9
y=2x/3+2
now this is or the form
y=mx+c where m is the slope nd c is the y intercept
so here 2/3 is the slope and 2 is the y intercept

-6x+9y=18
first you subtract the -6x then you get,
9y=6x+18
next, you divide the 6x+18 by 9
you now have, y= 2/3x+2
the y-intercept is 2 and the slope is 2/3

-6x + 9y = 18
then the slop is (-(-6)/9)
= 2/3
to get the intersect with y-axis
substitut with x=0
9y =18
y = 2
point of intersect (0,2)
