Draw the graph of $4x-3y+12=0$. From the graph, find the value of $x$ when $y=4$.

Draw the graphs of the equations $3x+4y=7$ and $3x-2y=1$ and find the point of intersection of the lines representing the equations.

At what point does the graph of the linear equation $2x+3y=9$ meet a line which is parallel to the $y-$axis, at a distance of $4$ units from origin and on the right of $y-$axis?

The linear equation which converts temperature from degrees in Celsius $\left(C\right)$ to degrees in Fahrenheit $\left(F\right)$ is given by $F=\frac{9}{5}C+32$. Draw the graph of the given linear equation using Celsius for $x-$axis and Fahrenheit for $y-$axis.
 

The linear equation which converts temperature from degrees in Celsius $\left(C\right)$ to degrees in Fahrenheit $\left(F\right)$ is given by $F=\frac{9}{5}C+32$. The temperature is $30°\mathrm{C}$. Then, if the temperature in Fahrenheit is $k°F$, find $k$.

The linear equation which converts temperature from degrees in Celsius $\left(C\right)$ to degrees in Fahrenheit $\left(F\right)$ is given by $F=\frac{9}{5}C+32$. The temperature is $95°\mathrm{F}$. Then, if the temperature in Celsius is $k°C$, find $k$.

The linear equation which converts temperature from degrees in Celsius $\left(C\right)$ to degrees in Fahrenheit $\left(F\right)$ is given by $F=\frac{9}{5}C+32$. If the temperature is $0°\mathrm{C}$, what is the temperature in Fahrenheit and if the temperature is $0°\mathrm{F}$, what is the temperature in Celsius?

The linear equation which converts temperature from degrees in Celsius $\left(C\right)$ to degrees in Fahrenheit $\left(F\right)$ is given by $F=\frac{9}{5}C+32$. Is there a temperature which is numerically the same in both Celsius and Fahrenheit? If yes, find it.
