2021年12月30日 · 原式相当于(12/2)x的省略。 那么为什么很多人很陷入错觉认为是2，因为x并不像123这种数字，而是个代数，解方程的时候经常接触，于是会习惯性的认为2x就是个整体，而实际上你算12÷2×2又会习惯性地从左往右算。

Reorder 12 12 and −2x - 2 x. Use the slope-intercept form to find the slope and y-intercept. Tap for more steps... Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps... Graph the line using the slope and the y-intercept, or the points.
