what is an equation for a line with a slope 1/2 and y-intercept of -11

The equation of the line with a slope of 1/2 and a y-intercept of -11 can be written in the slope-intercept form:

y = mx + b
where m is the slope, and b is the y-intercept.

So, substituting the given values, the equation becomes:
y = (1/2)x - 11
