100 nothe growth of baby girl claire is displayed in the graph below.

a) determine the slope of the line. show your work. (2 points)

b) is baby girl claire growing at a faster rate than baby girl grace? justify your answer. (2 points)

c) use point-slope form to write a linear equation to represent the growth of claire over time. then, simplify the equation and write it in slope-intercept form. identify the y-intercept. show your work. (3 points)

d) based on the data, how long was claire at birth? explain. (2 points)

answer:

a) slope: 4/5

find the difference of (4, 22) and (14, 30) which is (10, 8).

then place the rise over the run and simplify 8/10 = 4/5.

b) there isn't enough information here to tell, because you haven't given us baby girl grace's equation/graph.

c) the equation of the line can be represented by y= 4/5x + (y intercept).

fill in the rest of the equation with the slope you found to find it.

it is 18.8. so y = 4/5x + 18.8

d) baby claire was 18.8 inches long at birth.

step-by-step explanation:

i dont know i just need points

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
