Answer:
y=1/2x+1
Step-by-step explanation:
First use slope formula.

Plug in the information needed.

The slope is
.
Now, use point-slope formula.
y-y1=m(x-x1)
Plug in the information needed.
y-3=1/2(x-4)
y-3=1/2x-2
y=1/2x+1
The equation of the line in slope-intercept form is y=1/2x+1.

The answer is: " 10,000 cm " .
_________________________________________________
Note: 100 cm = 1 m (exact measurement); in which:
"cm" = centimeter(s) ;
"m" = meter(s) ;
_________________________________________________
100 m = ? cm ?
100 m * (100 cm / 1 m) = __?__ cm ;
The units of "m" cancel out; and we have:
(100)* (100 cm) = 10,000 cm .

According to the box and whisker plot, the answer must include a 15, 17, 20, 21, 22, 23 and 24
So, the first answer choice is correct.
Hope this helps.
