Question

Which is the equation of the trend line that is shown?

y=1/7x + 4/7

y = 1/7x + 16/7

y = 4/7x + 1/7

y = 4/7x - 1/7

Answer 1

one of the 4 equations, you should test your luck, but 2 is my favorite number so you should select the second one

Explanation:

Answer 2

y = 4/7x + 1/7.
Explanation: To find slope, you plug the two points into the equation (y2-y1)/(x2-x1). So, (7-3)/(12-5), or 4/7. This slope is then coefficient of x, showing 4/7x. You can clearly see that the y-intercept is positive, and infer that it is 1/7 based on the answer choices.
