What is the equation of the line that passes through the points (–2, 2) and (0, 5)?
A. y = 3/2x + 5
B. y = x – 5
C. y = –3/2x + 5
D. y = x + 5

Slope , m = y2-y1 /x2-x1 = 5-2/0-(-2) = 3/2; Equation of line, y = mx +c, substitute value (0,5) in equation, 5 = 0(3/2) + c , c =5, y = mx +c , substitute value of m and c , y = 3/2*x + 5, y =3/2 x +5

A series circuit contains a generator, two devices, and connecting wires. The resistances of the two devices are 15 ohms and 10 ohms. The voltage supplied by the generator is 75 V. The voltage drop in the device with 10 ohms of resistance will be 30 V.

Solution:

Voltage drop=Voltage * Resistor / total resistance

e = 75 * 10/25

e = 3 * 10

e = 30 V

Solution:

Voltage drop=Voltage * Resistor / total resistance

e = 75 * 10/25

e = 3 * 10

e = 30 V
