假定这条直线的方程为y＝kx＋b ∵在这条直线上，当x＝0时，y＝5 ∴b＝5 又 ∵ x＝2时，y＝0，代入原方程得 ∴0＝2k＋5 k＝-5／2
Line C slants down from left to right. Line C has a negative slope. Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. ...

It does not matter which points you use—the slope of the line is always the same. The slope of a line is constant!try itThe lines in the previous examples had yy -intercepts with integer values, so it was convenient to use the y-intercept as one of the points we used...
The gradient (also called slope) of a line tells us how steep it is. To find the gradient: Have a play (drag the points):
Cross-multiply to get 2c=3d. Divide both sides by 2 to get c=(3d)2. Next, use the given information to determine the equation of the lines. Use slope-intercept form: y=mx+b, where (x,y) is a point on the line, m is the slope, and b is the y-intercept. The first lin...
