Answer:
The answer to your question is 1
Step-by-step explanation:
Data
slope = m = -3
y-intercept = 3
Process
1.- Find the equation of the line in the slope-y-intercept form
y = mx + b
-Substitution
y = -3x + 3
2.- Find the x intercept
-If y = 0
0 = -3x + 3
-3 = -3x
-3/-3 = x
x = 1
-The x-intercept is 1
