A spark plug listed at $1.89, marked down 29%
N76 [4]
29% = 0.29

Multiply 1.89 with 0.29

1.89 x 0.29 = 0.5481

Note that it is a markdown, so subtract 0.55 (rounded) with 1.89

1.89 - 0.55 = 1.34

The spark plug now costs ~ $1.34

hope this helps

Answer:

D) y = -1/2x + 4

Step-by-step explanation:

Points on the graph: (0, 4) and (8, 0)

Slope:

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

m=(0 - 4)/(8-0)

m= -4/8

m = -1/2

Slope-intercept:

y - y1 = m(x - x1)

y - 4 = -1/2(x - 0)

y - 4 = -1/2x

y = -1/2x + 4
