Please help i don’t get this at all??

Okay this is pretty simple once you know how to do it.

if a line look like it is going uphill it is positive downhill and it is negative. This one look like it is going down so your slope is going to be negative. The line crosses the y-axis at -2 so -2 is the y-intercept. You can find the slope by doing rise over run. Pick any two points and you will see the the slope is 2/1 which is 2 but remember it is negative the answer is..

y= -2x - 2 which the would be B

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
