What is the slope of this line? -4,1 4,-1

Answer 1

To find the slope of a line given two points, you can use the slope formula:

$$m=\frac{y_2-y_1}{x_2-x_1}$$

In your case, the two points are (-4, 1) and (4, -1). We can assign the coordinates as follows:

• $(x_1,y_1)=(-4,1)$
• $(x_2,y_2)=(4,-1)$

Now, substitute the values into the slope formula:

$$m=\frac{-1-1}{4-(-4)}=\frac{-2}{4+4}=\frac{-2}{8}=-\frac{1}{4}$$

Thus, the slope of the line is $-\frac{1}{4}$.
