Find the slope between (2,10) and (9,1).

Answers

Answer 1

Answer:

The slope between (2,10) and (9,1) is -9/7.

We have given that,

(x1,y1)=(2,10) and(x2,y2)= (9,1).

What is the formula of the slope?

Slope=rise/run

Sope=y2-y1/x2-x1

use the given values in above formula so we get,

1-10/9-2=-9/7

So, the slope is -9/7.

What is 8 and 7/12 times 3

Answers

$8(7)/(12) = (103)/(12)$
3= $(36)/(12)$

$(103)/(12)$ × $(36)/(12)$ = $(3708)/(144)$ = $(103)/(4)$ =23.75

8 7/12 * 3

(8*12 + 7)/12 * 3

103/12 * 3

= 103 / 4

Answers

$(-7)/(12) = (y)/(-36)$

First, simplify $(y)/(-36)$ to $- (y)/(36)$ / Your problem should look like: $- (7)/(12) = -(y)/(36)$
Second, multiply both sides by 36. / Your problem should look like: $-21=-y$
Third, multiply both sides by -1. / Your problem should look like: $21 = y$
Fourth, switch your sides. / Your problem should look like: $y = 21$

Answer: C) 21
