Answer:
-3
Step-by-step explanation:
Draw a vertical line straight thru the point on the line (-3,1). Then draw a horizontal line straight thru the point (-1, -5). You'll see a triangle form. This is called a slope triangle. Calculate the slope by counting the units for the height and width of the triangle. The height is -6 and the width is 2. The slope is -6/2 = -3. The slope is negative since the line slants down from left to right.
