Answer:

Hi  , the answer is 280-140/ 4-2 = 140/2  

y = 2/140 x

b .  70 beats each minute

Step-by-step explanation:  

we will  take a 2 point from the graph

(280,4) , (y1,x1)    and (140, 2) , (y2,x2)      each point represent a (y,x)  point

m = y1-y2 / x1-x2   = 280-140 / 4-2 = 140 /2

now , y/x = 140/2 ... by B. Multiplication we will get y = 2/140 x  

b .

from the graph we see that every minute  the curve increase 70 beats

Thanks
