in mammal the weight of the heart approximately 0.5% total body weight write linear model that gives the heart weight in terms of body weight

Let the total weight of the body be = x

Let the weight of the heart of the mammals be = y

Now the given percentage of 0.5 %, we will convert it into decimal form,

so this is equal to 0.005 in decimal form,

so the linear equation that gives the heart weight in terms of body weight will be,

y = 0.005x
