8 1/2 is to 17 as 17 11 1/2 is to 23

Stella [2.4K]

Hello from MrBillDoesMath!

Answer: Yes, (8 1/2) /`17 = ( 17 11/12) /23

** I think you meant 11 1/2 is to 23 NOT 17 11 1/2 is to 23"

Discussion:

First, 8 1/2 = 17/2 and

(17/2 ) / 17 = 1/2

Second 11 1/2 = 23/2 and

(23/2)/ 23 = 1/2

IN other words, the ratiors are the same:

8 1/2 11 1/2

------- = -------

17 23

Thank you,

A linear function contains these points: (0,-1) & (3,8)

Elenna [48]

Answer:

slope: 3

y-intercept: (0, -1)

Find slope:

$\sf slope : \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{\triangle y}{\triangle x} \ \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

Here given points are: (0, -1), (3, 8)

$\rightarrow \sf slope : \dfrac{8-(-1)}{3-0} = \dfrac{9}{3} = 3$

When finding y-intercept, the value of x is 0. Here given y is -1 when x is 0.

y-intercept: -1 or (0, -1)
