Answer:

y = -3x - 2

Explanation:

If a line passes through (1.-5) and (-3, 7), the appropriate equation for the line in point-slope form is, y = -3x - 2.

Answer:

See below.

Step-by-stepexplanation:

The slope = rise/run

= (7- -5)/(-3-1)

= 12/-4

= -3

In point slope form:

y - y1 = -3(x - x1)

y - (-5) = -3(x - 1)

y + 5 = -3(x - 1) <--------- Point slope form.

y + 5 = -3x + 3

y = -3x - 2. <----------Slope-intercept form.
