Through (10-8) and (-1,2)

Question

a. 18x-3y=12

b. -18x+3y=12

c. 10x+11y=12

d. -10x+11y=12

Answer 1

The slope of the line through (10, - 8) and (-1,2) is [2-(-8)] / [-1-10] = -10/11.

 

Equation of line:  y - (-8) = -(10/11)(x - 10)

 

                         y + 8 = -(10/11)x + 100/11

 

                       11y + 88 = -10x + 100

 

                       10x + 11y = 12

 

Answer:  (c)
