Answer:
![y = -3x+6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/f25vxpf0brzakvk5sooyvv23zdu2xmxvt1.png)
Explanation:
Coordinates are (0,6) and (1,3)
Slope =
![(rise)/(run)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/3jp5d8vii932j341zjcsxym4by1d4hqy0c.png)
Slope =
![(3-6)/(1-0)](https://img.qammunity.org/2021/formulas/mathematics/middle-school/esb8yfoxswc6rtin0w086ixwzm05s6tu70.png)
Slope = -3
Now, Finding b
Taking any Point
Point = (x,y) = (0,6)
So, x = 0, y = 6
Putting in slope-intercept form to find b
![y =mx+b](https://img.qammunity.org/2021/formulas/mathematics/college/rccudsyridwsv2tntmghvjbqqrsnqw9jg3.png)
=> 6 = (-3)(0)+b
=> b = 6
Now Putting slope and b in the formula to get the required slope-intercept form.
![y =mx+b](https://img.qammunity.org/2021/formulas/mathematics/college/rccudsyridwsv2tntmghvjbqqrsnqw9jg3.png)
=>
![y = -3x+6](https://img.qammunity.org/2021/formulas/mathematics/middle-school/f25vxpf0brzakvk5sooyvv23zdu2xmxvt1.png)
