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
