Answer:
y = -2x.
Explanation:
The slope-intercept form of the equation of a line is:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
In this case, the slope is -2, and the y-intercept is 0. So we can substitute these values into the slope-intercept form of the equation:
y = (-2)x + 0
Simplifying, we get:
y = -2x
the equation of the line in slope-intercept form is y = -2x.
