Question

The graph of a linear equation in two variables is _____?
​

Answer 1

"a straight line"

Explanation:

recall that a linear equation may be expressed as

y = mx + b, where x and y are the variables (i.e 2 variables)

we also know that if we graph the linear equation y = mx+b, we will get a straight line.

Hence a possible answer for the blank could be:

"a straight line"
