Step-by-step explanation:
a)it isnt a linear equation because there are two variables but it is a linear equation in two variables
able
b)no it isnt ,there no variables
c)no the highest power of the variable 2,a linear equation should not exceed the ppwer by 1
d)there arent any variables.therefore it isnt a linear eqaution
e)no it isnt,there is no variable
f)yes,this is a linear equation
g)yes, this a linear equation in two variable , but not a linear equation in one variable
h)yes ,this is a linear equation in two variable in two variable but not a limear equation in one variable
