# Q10 Q12 At what point does line represented by the equation 8x + 4y = - 4. intersects a line which is parallel to the y-axis, and at a distance 3 units from the origin and in the negative direction of x-axis. In the graph of the linear equation 3x + 5y = 14, there is a point such that its ordinate is one third of abscissa. Find coordinates of the point. Find the equation of straight line which is parallel to x-axis, and is at a distance of d from x-axis. Shade the triangle formed by the graphs of 2x - y = 4, x+y=2 and the y-axis. Write the coordinates of the vertices of the triangle. The Auto fare in a city is as follows: For the first 2 Km, it is $25 and for the subsequent distance it is 10/Km. Taking the total distance covered as x Km and the total fare as '*y, write a linear equation for this information. Also calculate the total fare that a customer will have to pay for covering a distance of 20 Km. The weight of a father is three times the weight of his son. Write an equation in two variables for this situation and also draw the graph of the obtained equation.
