To write an equation in slope-intercept form for a line that passes through the origin with a slope of 2, we can use the slope-intercept form of a line, which is:
y = mx + b
where m is the slope of the line and b is the y-intercept, which is the point where the line crosses the y-axis.
Since the line passes through the origin, the y-intercept is 0, so we can write the equation as:
y = 2x + 0
Simplifying, we get:
y = 2x
This is the equation of a line with a slope of 2 that passes through the origin.
