Answer:

Explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

We know that the slope of this line is:

m=-(1)/(2)

And the y-intercept is:

b=-2

Since the line intersects the x-axis when
y=0 , we can substitute values into
y=mx+b :

0=-(1)/(2)x-2

The final step is to solve for "x", then:

$2=-(1)/(2)x\\\\(2)(-2)=x\\\\x=-4$
