remember... the y-intercept is the value of y when x=0;
-x +3y=15
0 +3y = 15
3y=15
y=5
therefore, the y-intercept is 5

for finding the y-intercept put x=0 and so 3y=15 and y intercept=5

to solve for the y intercept. x = 0
0 + 3y = 15
3y/3 15/3
divide 3 from both sides of the equation
y = 5
The y intercept equals 5

let x=0
-x+3y=15
substitute 0 to x:
-(0)+3y=15
3y=15
divide both side by 3:
3y/3=15/3
y=5

when finding the y-intercept set the x=0...
it will be -(0) + 3y = 15... then solve for y
i wont give the exact answer... :) solve for this part

-x + 3y = 15
3y = x + 15
y = (1/3)x + 5
in y = mx + b
b is the y-intercept
ANS : 5
