Which equation best represent the line of fit that is drawn?? A)
y=0.8x+15

B)
y=1.0x+10

C)
y=1.6x+8

D)
y=–0.8x +12

Choice B

y=1.0x+10

Explanation:

Without the actual (x,y) coordinates for each point, it's nearly impossible to get the answer. However, we can note that the blue regression line is intersecting the y axis at y = 10 (or around there). So its very likely that the answer is y=1.0x+10 which is choice B

The equation y=1.0x+10 is in the form y = mx+b with,

The next best answer is y = -0.8x+12, since 12 is fairly close to 10. The y intercept portion isn't fully shown but again it appears the blue line is crossing at y = 10.
