Question Text
Question 1 :
How many linear equations in x and y can be satisfied by x = 1 and y = 2?
Question 2 :
The point (0, 3) lies on the graph of the linear equation 3x + 4y = 12. State true or false.
Question 3 :
Find the solution of the linear equation x + 2y = 8 which represents a point on x-axis.
Question 5 :
If the temperature of a liquid can be measured in Kelvin units as x°K or in Fahrenheit units as y°F, the relation between the two systems of measurement of temperature is given by the linear equation $y = \frac {9}{5}$ (x - 273) + 32 . If the temperature is 158° F, then find the temperature in Kelvin.
