1 inch = 2.5 cm
how many cm is 18 inches
18 x 2.5
= 45
100
Is this linear or non linear why?
linear because the line is straight and it increases by the same amount.

which one is linear - figure (c) or figure (d) - and why
figure (d) is linear and figure (c) is non linear
figure (c) is non linear because it has a curve
figure (c) also increase and decreases
and figure (d) is linear because it is a straight line
and figure (d) increases by the same amount
