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 =

Answer 1

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:

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

The answer is:

the slope of the line is - 6
