sloperiseTUY2Y02-21a) Find the slope of a line that goes through the points (-2, 11), and (1, -7)m =b) The slope of a line is 3. The line contains the points (-1,8), and (x, 2).Then x =

Respuesta :

Step 01:

Data:

point 1 (-2, 11) x1 = - 2 y1 = 11

point 2 (1, -7) x2 = 1 y2 = -7

Step 02:

slope of the line:

[tex]m\text{ = }\frac{y2-y1}{x2-x1}=\frac{-7-11}{1-(-2)}=\frac{-18}{1+2}=\frac{-18}{3}=-6[/tex]

The answer is:

the slope of the line is - 6
