Hello :)
In order to find the x-intercept of a line substitute 0 into the y & solve for x
Since the line has a slope of -3 and a y intercept of 3 the equation would look like this:
y= -3x+3
Now we substitute 0 into the y & solve for x
0 = - 3x + 3
+3x +3x
[tex]\frac{3x}{3}=\frac{3}{3}[/tex]
x=1
The answer here would be c) 1
