"NettetFirst write 3 x-y=2 in the slope-intercept form, y=mx+b, by solving for y, getting 3 x-y=2. This result shows that the Slope is m=3 and the y -intercept is b=− 2. To draw the graph, first locate the y -intercept. See Figure 3.15. Then, as in Example 5, use the slope of 3, or 31, to get a second point on the graph. " - Linear relationship gradient

Nettet5. sep. 2024 · The gradient of a line or slope involves a lot of things in mathematics. At its most basic, the slope informs you how fast a line rises or falls on a graph. This little bit of information can help you comprehend the data behind the line, specifically in terms of the relationships between values. NettetThe hydraulic gradient is the driving force that causes groundwater to move in the direction of maximum decreasing total head. It is generally expressed in consistent units, such as feet per foot. For example, if the difference in water level in two wells 1000 feet apart is 2 feet, the gradient is 2/1000 or 0.002 ( Fig. 3-12 ).
