Question

are the points (1,0),(0,3),(-1,6),(2,-3) lie on the same straight line? If so find the equation of the line ​

Answer 1

Answer:

As all the 4 points lies on the same line so we have to find the equation of line,

but to find equation of any line we must have two points required so that we can apply two point form and find the equation of the given line .So ,we will take two points and apply two point form as shown in attachment.

After finding the equation of the line we will put the coordinates of rest two points in the equation of the line and if they both satisfy the equation then it will be concluded that all lie on same line and if they not do so then they don't lie on same line .
