I need help with this equation for math

The answer would be B

Step-by-step explanation:

the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.

y = -1/2x +4

Step-by-step explanation:

We have two points so we can find the slope

m = (y2-y1)/(x2-x1)

   = ( 0-4)/(8-0)

   = -4/8

   = -1/2

We know the y intercept is 4

The slope intercept form of the line is

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

y = -1/2x +4

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
