Answer 1

The equation of the line is y = -x + 9.

Explanation:

First, you have to find the gradient by choosing any 2 coordinates that lies on the line. I will choose (0,9) and (9,0). Then you have to substitute it the the formula.

`m = (y2 - y1)/(x2 - x1)`

`let \: (x1,y1) \: be \: (9,0) \\ let \: (x2,y2) \: be \: (0,9)`

`m = (9 - 0)/(0 - 9)`

`m = (9)/( - 9)`

`m = - 1`

Next, you have to put into the slope-form equation, y = mx + c where m represents gradient which is -1 and c is y-intercept. In order to find c in a faster way, you can look at the graph to see which coordinates touches y-axis. So the value of c is 9 :

`y = - x + 9`
