Question

plot a line graph for the variables X and Y where Y is equal to 2 X + 1.Using the graph find the value of Y, when x is equal to 5 and X, when Y is equal to 13.​

Answer 1

Answer:

Y=2X+1

LET TAKE X=0 THEN Y= 2(0)+1 =1

TAKE X=1 Y= 2(1)+1 =3

X=2 Y=2(2)+1 =5

Similarly X=5 Y= 2(5)+1 = 11
