b) part

Mehek (mehek14):

choose 2 points from the chart

OpenStudy (winsteria):

8 (from months) and 23 (from length)?

Mehek (mehek14):

oke (8,23) another one?

Mehek (mehek14):

oke (8,23) and (12,26) \(\dfrac{26-23}{12-8}=?\)

OpenStudy (winsteria):

3 - 4

Mehek (mehek14):

so slope = \(\dfrac{3}{4}\)

Mehek (mehek14):

\(y=\dfrac{3}{4}x+b\) \(23=\dfrac{3}{4}*8+b\) solve for b

OpenStudy (winsteria):

83 - 4

Mehek (mehek14):

\(\dfrac{3}{4}*\dfrac{8}{1}\)

OpenStudy (winsteria):

6

Mehek (mehek14):

3*8 = 24 24/3 = 8 not 6

Mehek (mehek14):

now subtract 23 - 8 = ?

OpenStudy (winsteria):

15

Mehek (mehek14):

so b = 15 \(y=\dfrac{3}{4}x+15\)

OpenStudy (winsteria):

Is that my equation?

Mehek (mehek14):

ye

OpenStudy (winsteria):
