If this is work out the gradient then here:</h2>
Step-by-step explanation:
3-0= 3
2-(-2)= 4
3/4= 0.75
<h3>Equation of a gradient is </h3><h2>

</h2>
If y=8-x then you can plug that into the equation like 7=2-(8-x). When you distribute the equation becomes 7=2-8+x. Once you combine like terms the equation becomes 7=-6+x. Then you subtract 6 from both sides, which gives you 13=x.
To find y just put 13 where x was in the first equation. Y=8-13.
Y=-5
X=13
