What is a two variable linear equation

see below

Step-by-step explanation:

It's an equation that has two variables

that's to say it has x and y (generally)

it is linear when you graph it, it forms a line and that only happens when the mayor exponent is one

so

notice all the something are completely different

or you could find it as

where m is the slope

and b some number

so that's it

if x = 1, then the answer is 3.5
