Rewrite as 3y = 15+x
y= (x/3)-5 for x=0 the intercept is 5

The y-intercept for -x+3y=15 is when x=0:
-(0)+3y=15
3y=15
y=5
The y-intercept is P(0, 5)

Find the y intercept
x = 0
- x + 3y = 15
0 + 3y = 15
3y/3 = 15/3
y = 5
The answer: When x = 0, the y intercept is 5

To find the y-intercept, x must be equal to zero.
Thus,
-x+3y=15
-0+3y=15
3y=15
y=15/3
y=5
So the y-intercept is 5. The coordinate of y-intercept is (0,5)

-x+3y=15
3y = x+15
y = â
x + 5
For a linear equation which in the form of y=mx+c, m is the gradient and c is the y-intercept.
Hence, y-intercept = 5
====Alternative Method====
-x+3y=15
At y-axis, x=0
-0+3y=15
y=5
Hence, y-intercept = 5

For y-intercept express the equation of the line in
y=mx+c format.
where 'm' is the slope and 'c' is the y-intercept.
3y=15+x
y=(x/3)+5
c=5 which is your y intercept that is (0,5)
