Question

Find a relation between x and y if the points (x,y) (1,2) and (7,0) are collinear

Answer 1

Collinear is a topic under coordinate geometry. When points are said to be collinear it means it's gradient (m) are equal. The formula is the y-axis divided by the x-axis for the the first two points =that of the next two points this will give you 2x-6y+10=0
