You can use the formula
M= y2 - y1 is divided by x2-x1

The graph is saying the first point is 4,2 and the second point is 6,1

The first number is the x value and the second value is the y value.
So in this case, y2 is -1 and y1 is 2
So you are doing -1-2 which is equal to -3
Then for the x values, x2 is 6 and x1 is 4. So you would do 6-4 which is 2.
So since y has to be on top and x is on the bottom, it would be -3/2.
So, the equation is:
M= -3/2

Answer:


\sf y +1 = (-3)/(2)(x - 6)

Explanation:

The point-slope form of the equation of a line is given by:


\sf y - y_1 = m(x - x_1)

where
\sf (x_1, y_1) is a point on the line, and
\sf m is the slope of the line.

Let's use the given points
\sf (6, -1) and
\sf (4, 2) to find the equation.

First, find the slope (
\sf m) using the formula:


\sf m = (y_2 - y_1)/(x_2 - x_1)

Substitute the coordinates
\sf (x_1, y_1) = (4, 2) and
\sf (x_2, y_2) = (6, -1) into the formula:


\sf m = ((-1 - 2))/((6 - 4))


\sf m = (-3)/(2)

Now, choose one of the points, let's say
\sf (4, 2), and substitute into the point-slope formula:


\sf y - (-1) = (-3)/(2)(x - 6)


\sf y +1 = (-3)/(2)(x - 6)

So, the equation in point slope form is:


\sf y +1 = (-3)/(2)(x - 6)
