If the straight line y = mx + c passes through the points (2, 4) and (–3, 6), find the values of m and c.
None of these
Since (2, 4) lies on y = mx + c
Again (–3, 6) lies on y = mx + c
Solving (i) and (ii), we get
Find whether the points (–a, –b), [–(s + 1)a, –(s + 1)b] and [(t – 1)a, (t – 1)b] are collinear?
For what value of k the points (k, 2 – 2k), (–k + 1, 2k) and (–4 – k, 6 – 2k) are collinear?
