if(2,3) and (4,0) lie on the graph of equation ax+by=1. find the value of a and b and plot the graph of the equation obtained

(2,3) and (4,0) lie on *ax* + *by* = 1.

∴ (2,3) and (4,0) will satisfy *ax *+* by* = 1

∴ Equation becomes

We get the table as follows:

x | 0 | 2 | 4 |

y` | 6 | 3 | 0 |

Plotting the graph:
