The equation of a straight line is written as
y = mx + c
Where
m represents slope
c represents y intercept
The given equation is expressed as
3x + y = 3
y = 3 - 3x
y = - 3x + 3
Comparing the above equation with the slope intercept equation,
y intercept = 3
The x intercept is the value of x when y = 0
Putting y = 0 in the equation, it becomes
0 = - 3x + 3
3x = 3
x = 3x/3
x = 1
x intercept = 1
