We are given two points on a line. First we need to find the slope of the line using these two points.
The given points are (6, 1) and (5, 4). The slope (m) of the line will be:
Using the slope and the point (6,1) we can write the equation in point slope form as:
y - 1 = -3(x -6)
y = -3x + 18 + 1
y = -3x + 19
In standard form, the equation will be:
3x + y = 19

Answer:
1.
Step-by-step explanation:
We have been given a graph of a scatter-plot and we are asked to find the correct expression than can be solved to find the slope of the trend line in the scatter-plot.
Since we know that slope of a line can be found by dividing the difference of the y-coordinates of 2 points on a line by difference of the x-coordinates of these same points.
We can see that (2,79) and (12,24) are two given points of our trend line. So let us substitute x and y-coordinates of our given points in slope formula to find the our desired expression.
Therefore, the expression can be solved to find the slope of the trend line in the scatter-plot and 1st option is the correct choice.
