PLEASE TELL ME HOW TO DO IT Draw the graph of the equation y = 2x + 3. From the graph find the value of y when

(i) x = -3
(ii) x= 9
I want the answer...........

Graph of the equation y =2x+3 be as,

 From the graph, 

(1) when x =-3, we get y = -3

(2) and when x= 9 , we get y =21

And you can find from the equation also,

when x = -3,

y = 2(-3) + 3 = -3

And, when x = 9

y = 2(9) + 3 = 21
