Answer:
gracey
Step-by-step explanation:
find the equation of both graphs:
for gracey, she increases by 4 pounds every week, so her slope is 4, she starts out at 1 lb so b=1, so her graph is y=4x+1
for luna, she increases by 3 pounds every week, so her slop is 4 and she starts out at 2 lbs so b=2, her graph is y=3x+2.
plug in 5 for x in both equations to find out which y-value is greater, for gracey, y=21, for luna, y=17. 21>17 so gracey will weigh more at 5 weeks
