Since you want to find the y-intercept put 0 for x and solve the equation:
5x+y=5
5(0)+y=5
y=5
So the y-intercept is 5

Always remember, the point where the line crosses the y axis (the y intercept) is when x = 0. So, in the equation 5x+y = 5
y = 5

To find the y-intercept, you can either put the equation into slope-intercept form (y = mx + b), where b is the y-intercept, or you can let x = 0 and solve for y.
In slope-intercept form...
5x + y = 5
y = -5x + 5
So b = 5.
Or letting x = 0...
5(0) + y = 5
0 + y = 5
y = 5
So you can also see here it is equal to 5.
For the x-intercept, you let y = 0 and solve for x.

Put the equation in slope-intercept form: y = mx + b
y = -5x + 5
The y intercept is 5, the slope is -5

putx=0,we get,y=5 this is the y-intercept.

plug 0 for y...
5x=5 so x =1

5x+y=5
Subtract 5x on both sides and you get y=-5x+5
y=ax+b
b=y intercept
y intercept=5
