www.ncert.nic.inThere will be two straight lines, both to be considered together . You have also studied in Class IX that given two lines in a plane, only one of the following three possibilities can happen: (i) The two lines will intersect at one point. (ii) The two lines will not intersect, i.e., they are parallel. (iii) The two lines will be coincident.
Equations of straight lines
www.mathcentre.ac.ukthe gradient would be −2. In general, therefore, the equation y = mx represents a straight line passing through the origin with gradient m. Key Point The equation of a straight line with gradient m passing through the origin is given by y = mx. 3. The yintercept of a line Consider the straight line with equation y = 2x+1.

www.mathcentre.ac.ukThe equation of a straight line with gradient m passing through the origin is given by y = mx. 3. The yintercept of a line Consider the straight line with equation y = 2x+1. This equation is in a slightly different form from those we have seen earlier. To draw a sketch of the line, we must calculate some values.

Load line analysis for a diode circuit
neurophysics.ucsd.eduLoad line analysis for a diode circuit (I versus V D) A plot of the current, I, versus the voltage drop across the diode, V D, will yield a straight line, called the "Load Line", of possible values of current flow in the circuit. We form the line by noting that I = 0 at V D = V S and that I = V D/(R S + R L) at V S = 0, as shown below:

Greenhouse Gases CHAPTER 4
forecast.uchicago.edu2 molecule is shaped in a straight line with carbon in the middle (Figure 4-1). Oxygen tends to pull on electrons more tightly than carbon does, but the oxygen atom on one side pulls the electrons just as tightly as the other oxygen on the other side. The molecule has no permanent electrical field asymmetry (dipole moment).
