Clarise bought a 3 month-old kitten that weighed 4 pounds. Each month, the kitten gained 0.5 pounds when he was weighed at the vet's office. If x represents the number of months and y represents the weight of the kitten, which equation in point-slope form, y−y1=m(x−x1), models the situation? y−3=0.5(x−4)
y minus 3 is equal to 0 point 5 times open paren x minus 4 close paren

y−4=0.5(x−3)
y minus 4 is equal to 0 point 5 times open paren x minus 3 close paren

y−0.5=3(x−4)
y minus 0 point 5 is equal to 3 times open paren x minus 4 close paren

y−4=3(x−0.5)
