绘制线性图像
Plotting Linear Graphs
通过生成数值表来绘制线性图像,将二元线性方程化为 y = mx + c 的形式,并利用直线上的两点计算斜率。
Plot linear graphs by generating a table of values, reduce a two-variable linear equation to the form y = mx + c, and calculate gradients from two points on a line
学习证据 / Evidence
- 为线性方程生成一组 (x, y) 数值表,并准确地描点。
- 将诸如 2x + 3y = 12 的方程改写为 y = mx + c 的形式。
- 利用纵坐标变化量除以横坐标变化量,计算两个坐标点之间的斜率。
- Generate a table of (x, y) values for a linear equation and plot the points accurately
- Rearrange an equation such as 2x + 3y = 12 into the form y = mx + c
- Calculate the gradient between two coordinate points using rise over run
