Question

Is 3(exponent2)+2y=x a linear equation? If not, why?

Answer 1

3*3=9
9+2=11 so remeber this

It has one or two variables.
No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make the linear equation true and plot those pairs on a coordinate grid, all of the points for any one equation lie on the same line. Linear equations graph as straight lines.
