Question

Use the image to answer the question.

An illustration of a scatterplot graph shows x-axis ranging from 0 to 10 in increments of 1 and y-axis ranging from 0 to 50 in increments of 10. Multiple points are plotted around a line that points downward to the right with an arrowhead on the bottom.

Write an equation in slope-intercept form of the trend line.

(1 point)
y=

x +

Incorrect

Look at whether the trendline goes up or down. This will tell you whether the slope is positive or negative.
Look for the place where the trend line crosses the y-axis.

Answer 1

I can’t see the exact trendline detail from your description, so I don’t want to guess and use up your attempts. Could you either upload the image or tell me two clear points the trendline goes through (preferably grid intersections), for example the y‑intercept (where x=0) and one other point like (10, y)?

How you (or I) will get the equation once you give two points (x1,y1) and (x2,y2):

1. Compute slope m = (y2 − y1)/(x2 − x1).
2. Use y = mx + b and plug in one point to solve for b (the y‑intercept).
3. Write the final equation y = mx + b.

If you prefer, tell me what y value the line crosses at x = 0 and what y value it has at x = 10 and I’ll compute the equation.
