Question

A scatter plot with 14 data points and an orange downward-sloping regression line.
Write an equation in slope-intercept form of the trend line.

(1 point)

y=5.67x+8


y=15x+8


y=−15x+8


y=−15x+3

Answer 1

I can't see the plot — could you upload the image or tell me two clear points on the orange trend line (for example the y-value where it crosses the y-axis and one other point)?

If you can read two points (x1,y1) and (x2,y2), compute:
- slope m = (y2 − y1) / (x2 − x1)
- intercept b = y1 − m·x1
Then the trend line is y = m x + b.

If you can't upload but can estimate where the line crosses the y‑axis: if it crosses near y = 8 pick y = −15x + 8; if it crosses near y = 3 pick y = −15x + 3. (The other two choices have positive slopes, which contradict “downward‑sloping.”)
