Answer:
y = x/2 - 19 linear
3y = x^2 not linear
13y = 1/3 x+5 linear
y = x+25/5 linear
y^3 =x not linear
Step-by-step explanation:
We know that if the function is of the form y= mx+b it makes a line.
If the y term and the x term are both in the numerator and to the power of 1 and not multiplied by each other, then it is linear.
y = x/2 - 19 linear ( y = mx+b)
3y = x^2 (x is to the power of 2 ) not linear
13y = 1/3 x+5 linear (y = mx+b)
y = x+25/5 linear (y = mx+b)
y^3 =x (y is to the third power) not linear
