Answer:

y = –10x + 70

Explanation:

To find the line's equation in slope-intercept form, use the slope-intercept formula:

y = mx + b

Where:

m = slope

b = y-intercept

Then, find the y-intercept first. The y-intercept is the point where the line intersects the y-axis. You can see on the graph that it intercepts the y-axis at (0, 70).

So, b = 70.

Then, find the slope. The slope is the steepness of the line and you can find it by using rise-over-run. The slope formula is:

y2 – y1

m = _______

x2 – x1

Plug in any two coordinates. In this case, you can use (2, 50) and (4, 30).

30 – 50

m = _______

4 – 2

–20

m = _______

2

m = –10

This means that the change in y over x is –10 over 1.

You plug in the y-intercept and slope into the slope-intercept formula to get the final result:

y = –10x + 70
