A straight line has equation y = mx + c, where m and c are constants.

(a) The point (2,7) lies on this line. Write down an equation in m and c to illustrate this information.

(b) A second point (4, 17) also lies on this line. Write down another equation in mc and c to illustrate this information.

(c) Hence calculate the values of m and c.

(d) Write down the gradient of this line.


Can you explain to me how to do this? Thanks!
