You can put this solution on YOUR website! Complete the following statements with never, sometimes, or always.
1. There are always_ an infinite number of solutions to a two variable equation in standard form.
---------------------------------------------------------------------------
2. The graph of a linear equation sometimes__ has an x-intercept.
y=3 does not have an x-intercept.
---------------------------------------------------------------------------
3. If y varies directly with x, the constant of variation k is sometimes __ negative.
Direct variation: y = kx
If x = -3 when y = 9, k = -3
If x = 3 when y = 9, k = 3
--------------------------------------------
