Generate and plot ordered pairs from rules, tables, and contexts.
Turn graphing words into coordinates or a rule
Problem
Evaluate \(y~=~2x\) at \(x~=~1,~2,~\text{and}~3\), then report the complete ordered-pair list to plot.
Big Picture
What this problem is really about
The phrase two times x describes multiplication, not addition, exponentiation, or a constant output. Translate it into a symbolic relationship, substitute each requested x-value separately, and keep each result paired as x first and y second. This preserves both the operation named by the words and the coordinate order needed for plotting.
