Help but explain good how to solve this question

The line has a slope of -7/6

Step-by-step explanation:

To find the slope of a line, you only need two of its points.  Slope is defined as the difference along the y axis divided by the difference along the x axis.

So let's take any two points, and find that slope.  We'll use (-8, 8) and (-2, 1):

So the slope of the line -7/6

11) obtuse

13)right

15) acute

answer: the up tack or falsum is a constant symbol used to represent a logical constant denoting "false" in logic.
