Answer 1

Answer:

for this,we have to show the collinearity of the given points-

A(4,2) B(7,5). C(9,7)

If slope of AB= slope of BC= slope of AC,then points are collinear

slope AB= 5-2/7-4=1

slope BC=7-5/9-7=1

slope AC=7-2/9-4=1

Here all slopes are equall so points are collinear i.e,lie in same straight line
