What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?

Question

i dont understand

 

Answer 1

The "General Form" of the equation of a line looks like:  Ax + By + C = 0

 

The slope-intercept form of the equation of a line looks like:   y = mx + b

     where m=slope     and    b is the y-intercept

 

y = -2x + 8      ["slope of -2 and a y-intercept of 8"]

 

2x + y - 8 = 0          [add 2x to both sides; subtract 8 from both sides]

Answer 2

In slope-intercept form:

y = -2x + 8

In standard/general form:

2x + y = 8
