Question

Draw the graph of the equation 2x+3y=12. Find the solutions from the graph
i) Whose y-coordinate is 3
i) Whose x-coordinate is -3

​

Answer 1

Step-by-step explanation:

(I) if y coordinate is 3

then 2x+3y=12

2x+9=12

2x=3

X=3/2

(ii)if X coordinate is -3

then 2x+3y=12

-6 +3y =12

3y=18

y=6

solutions of this graph= (3/2,3) and (-2,6)
