The number of messages sent by Elsa, Ryan and Jim are 11 , 84 and 21 respectively.
<em><u>Explanation</u></em>
Suppose, the number of messages Jim sent is
As Ryan sent 4 times as many messages as Jim, so the number of messages sent by Ryan
Also, Elsa sent 10 fewer messages than Jim, so the number of messages sent by Elsa
Given that, they sent a <u>total of 116</u> text messages. So the equation will be.......
So, the number of messages sent by each of them.....

The point-slope form of the line that passes through (6,1) and is parallel to a line with a slope of -3 is 3x + y – 19 = 0
<u>Solution: </u>
The point slope form of the line that passes through the points and parallel to the line with slope “m” is given as
--- eqn 1
Where “m” is the slope of the line. are the points that passes through the line.
From question, given that slope “m” = -3
Given that the line passes through the points (6,1).Hence we get
By substituting the values in eqn 1, we get the point slope form of the line which is parallel to the line having slope -3 can be found out.
y – 1 = -3(x – 6)
y – 1 = -3x +18
On rearranging the terms, we get
3x + y -1 – 18 = 0
3x + y – 19 = 0
Hence the point slope form of given line is 3x + y – 19 = 0
