Points (1.1,3.3) and (-2,7.2);

You could start with point-slope form, and say ; continue from that.

a linear function
given:
=>,, that is a point (,)

=>, that is a point (,)

use given points and set system of equations:

....substitute ,
........solve for
......eq.1

....substitute ,

.....eq.2

equal the left sides of eq.1 and eq.2 and solve for






go to eq.1 and substitute
......eq.1



and your equation is:



check the graph:
