What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8? a. x + 2y - 8 = 0 b.2x + y - 8 = 0 c.2x - y + 8 = 0

Step-by-step explanation:

The slope-intercept form of an equation of a line:

m - slope

b - y-intercept

We have the slope m = -2 and the y-intercept b = 8. Substitute:

The general form of an equation of a line:

Convert:

             add 2x to both sides

             subtract 8 from both sides

the radius is 2 times the diameter.
