WebTAILS Method of Interpreting Graphs How to Interpret Math (in other words, steps to reading ANY graph): 1. Read the title. 2. Identify the Independent (x-axis) and Dependent (y-axis) variables. 3. Determine the units of the x and y-axis. 4. Determine the size of each division on the x and y-axis. 5. Determine what the slope tells us (if ... WebIf the linear equation has two variables (X and Y), then it will have both an x-intercept and a y-intercept. They can turn out to be one point if the line happens to go thru the origin (0,0). If the linear equation is of the form: X = a number, then it is a vertical line and it has an x-intercept, but no y-intercept.

WebJan 31, 2024 · The Chirp Spread Spectrum (CSS) based wireless communication has been widely used in Wireless Sensor Network (WSN). These sensors generally have slow speed, and is becoming more demand for higher data rate. However, due to the low transmission rate of CSS, there are still many problems to be studied. WebSep 27, 2024 · A graph can easily be prepared by using standard solutions to determine the concentration of a specimen. The graphing method assumes a straight-line relationship between concentration and absorbance, which is valid for dilute solutions. Figure 1.1. In above Figure 1.1 graph shows that the concentration is directly proportional to absorbance.
