Question

Write the equation of the line that passes through the points (7,9) and
(9,-2). Put your answer in fully reduced point-slope form, unless it is
a vertical or horizontal line.

Answer 1

Step-by-step explanation:

9 = a7 + b

-2 = a9 + b

b = 9-7a and b = - 2-9a

9 - 7a = - 2-9a

2a = - 11

a = - 5.5

b = 9 - 5.5*7 = - 29.5

y = -5.5x - 29.5
