Answer:
1
Explanation:
If we know the slope and the y intercept, we can use the slope intercept form to write the equation
y = mx+b where m is the slope and b is the y intercept
y = -3x +3
We want to find the x intercept
Set y = 0 and solve for x
0 = -3x+3
Subtract 3 from each side
-3 = -3x
Divide each side by -3
-3/-3 = -3x/-3
1 =x
The x intercept is 1
