Answer:
what
Step-by-step explanation:
Answer:
find gradient/slope
-8-(-5) / -2-(-1) = -3/-1
= 3
y=3x+c
perpendicular line formula
m1(m2)= -1
(sub in the gradient before)
3(m2)= -1
m2= -1/3 ( perpendicular line gradient)
y=-1/3x+c
(sub in the coordinate)
-5=-1/3(-3/2)+c
-5=1/2+c
-11/2=c (y intercept)
answer: y= -1/3x - 11/2
Answer:
A
Step-by-step explanation:
Go to the graph at 12 weeks and the line for Baby A is above Baby B.
Each number has a factor of 2, so divide each number by 2, giving you 2:11:15. You can't divide by anything else because 2, 11, and 15 have no factors in common.
