The equation of the line in slope - intercept form is
y=-3x+1

Step-by-step explanation:

From the graph, the given coordinates are
(-1,2) and
(1,-4)

We need to determine the equation of the line in slope intercept form.

The equation of the line can be determined using the formula,


y-y_1=m(x-x_1)

First, we shall find the value of the slope.

The slope can be determined by substituting the points
(-1,2) and
(1,-4) in the slope formula, we get,


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


m=(-4-2)/(1+1)


m=(-6)/(2)


m=-3

Thus, the slope is
m=-3

Now, we shall substitute the coordinate
(-1,2) and the slope
m=-3 in the formula
y-y_1=m(x-x_1), we get,


y-2=-3(x+1)


y-2=-3x-3


y=-3x+1

Thus, the equation of the line in slope intercept form is
y=-3x+1
