Answer:

Step-by-step explanation:

Given points ( 7 , 20) and ( -2 ,11)

First calculating slope

Slope (m)

= ( y2 - y1)/ (x2 - x1)

= ( 20 - 11) / ( 7 + 2)

= 9/9

= 1

Now the equation of line is given by

y - y1 = m( x - x1)

y - 11 = 1( x + 2)

y - 11 = x + 2

x - y = - 11 - 2

x - y = - 13

x - y  + 13 = 0

Hope it will help :)

Answer:

Step-by-step explanation:

y-20=(11-20)/(-2-7)(x-7)

y-20=-9/-9  (x-7)

y-20=x-7

y=x-7+20

or y=x+13
