Question

The line graphed below has a slope of

-3
- 1/3
1/3
3

Answer 1

The slope is -3

Explanation:

We have two points (-3,1) and (-1, -5)

We can use the formula for slope

m = (y2-y1)/(x2-x1)

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

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

=-6/2

=-3

Answer 2

-3

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.
