Question

The vertices of a triangle are J(-3,2), K(1,1), and L(-1,-7). Calculate the slopes of the lines connecting the vertices. Then, determine whether the triangle is a right triangle.

The slope of the line connecting points J and K is ____.

Answer 1

The slope of the line connecting points J(-3, 2) and K(1, 1) is -1/4.

Step-by-step explanation:

To calculate the slope of the line connecting points J(-3, 2) and K(1, 1), we can use the formula for slope which is given by:

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

Substituting the coordinates into the formula, we have:

slope = (1 - 2) / (1 - (-3)) = -1/4

Therefore, the slope of the line connecting J and K is -1/4.
