What is the equation of a line, in general from, 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

Answer:B

Step-by-step explanation:move the 2x (which represents the slope) to the other side and it becomes - 2x which you want, and then move the - 8 over to the other side as well. So it becomes a positive 8 and the final equation would be y=-2x+8
