Help me please ?!!!!

Answer 1

The slope of the line is -1

Explanation:

Slope of a Line

Suppose we know a given line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated as follows:

`\displaystyle m=(y_2-y_1)/(x_2-x_1)`

From the table in the image, we select the points (1,4) (3,2). The slope is:

`\displaystyle m=(2-4)/(3-1)=(-2)/(2)=-1`

Now select two other points like (5,0) (7,-2)

`\displaystyle m=(-2-0)/(7-5)=(-2)/(2)=-1`

Following the same procedure with any other pair of points, we'll get the very same result:

The slope of the line is -1
