Question

Find the equation of the line shown.​

Answer 1

The answer is y=-x+9

Answer 2

y = -x + 9

Step by step explanation:

In order to write the equation of the line, we can write it in slope intercept form
`y=mx+b` where m is the slope and b is y intercept. Judging by the graph, we can see that the line is passing through (0,9) which makes that our y intercept.

To find the slope, we can count the slope using
`(rise)/(run)` or using the slope formula. For the sake of simplicity, we will count the slope, Counting the slope, we get
`(-1)/(1)` or simply
`-1`. Now we just have to plug our numbers into the formula.

`y=-x+9`
