估算答案（13岁及以上）
Estimating answers (age 13+)
利用一次函数和二次函数的图像，估算给定输入对应的输出值，求方程的近似解，并在实际情境中解读图像信息。
Use graphs of linear and quadratic functions to estimate output values for given inputs, find approximate solutions to equations, and interpret graphical information in real-world contexts
学习证据 / Evidence
- 从绘制的曲线上读出给定x对应的近似y值。
- 通过确定图像与x轴或另一条直线的交点，求方程的近似解。
- 解读实际情境中的图像（如距离—时间图）来回答与情境相关的问题。
- Read off an approximate y-value for a given x from a plotted curve
- Find approximate solutions to an equation by identifying where a graph crosses the x-axis or another line
- Interpret a real-world graph (e.g., distance–time) to answer contextual questions
评估问题 / Assessment
{{name}}能否利用图像（无论是直线还是曲线）来近似读出方程的解，而不是通过代数方法求解？
Can {{name}} use a graph — whether a straight line or a curve — to read off an answer to an equation approximately, rather than solving it algebraically?
