Answer:
x-intercept: 1
C is correct
Explanation:
A line has a slope of –3 and a y-intercept of 3
Slope (m) = -3
y-intercept: (0,3)
Using slope and y-intercept we will make the equation of line.

Equation of line:


Now we will find x-intercept
For x-intercept put y=0


x-intercept: (1,0)
Hence, The x-intercept of the equation is 1
