Question

The points (3,0) , and (0, -4) lie on the graph of the equation ax -by =12 .What are the values of a and b respectively ?​

Answer 1

Answer:

just put the values of x and y in the equation

a=4

b=3

Step-by-step explanation:

firstly for (3,0)

x=3, y=0;

put in equation ax-by=12

we get,

3a-0y=12

3a=12

a=4

similarly for (0,-4),

we get,

0a-b(-4)=12

4b=12

b=3
