Answer:
The slope of line for given points is
Step-by-step explanation:
Given points of line as :
A = ( - 7 , 15 ) i, e = - 7 ,
= 15
B = ( 10 , 27 ) i.e = 10 ,
= 27
Let The slope of line be m
So , The slope with two points is given as equation
m =
Or, m =
Or, m =
Hence The slope of line for given points is . Answer
