The equation of the line passing through the points (-1,6) and (3,-2) in slope-intercept form is y = -2x + 4.

By using the graph we can identify the two points are (-1,6) and (3,-2)

To write the equation of a line in slope-intercept form, we need two pieces of information: the slope of the line and the y-intercept.

The points (-1,6) and (3,-2), we can find the slope using the formula:

slope = (change in y) / (change in x)

Substituting the coordinates of the two points:

slope = (-2 - 6) / (3 - (-1))

= -8 / 4

= -2

Now that we have the slope, we can use the point-slope form of the equation:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope.

Using the point (-1,6) and the slope -2:

y - 6 = -2(x - (-1))

y - 6 = -2(x + 1)

y - 6 = -2x - 2

y = -2x + 4

Therefore, the equation of the line passing through the points (-1,6) and (3,-2) in slope-intercept form is y = -2x + 4.
