I am really stuck on this question, any help would be greatly appreciated!
Thanks! Answer by Ave(106) (Show Source):
You can put this solution on YOUR website! so if acre is x that would make snakes y so lets make a couple of ordered pairs
(24(acres),11(snakes)) and (49(acres), 13(snakes))
(24,11) and (49,13) lets find the slope
(13-11)/(49-24)
2/25=slope
Use point slope form to find an equation slope 2/25, (24,11) multiply both sides by 25 to get rid of the fraction
25y-275=2(x-24)
25y-275=2x-48 add 275 to both sides
25y=2x+227 divide by 25 <--slope intercept form
or <--standard form
