Answer:
The first one, or y= -x + 8
Step-by-step explanation:
You can rule out the last one, because there is no y intercept. If there was no y intercept, the dots would be passing through the origin (0).
The one with -8 is not right because the y intercept is positive 8. If you count on the y axis (up 8), it matches with the overall direction of the line.
The line/ slope of this scatter plot is negative, so the only one that makes sense would be the first one. Going up and from right to left is a positive slope. Going down from left to right is a negative slope.
