Which of the points (0, 0) (0, 4) or (– 1, 4) is a solution of the equation? 3. Look at the following graphical representation of an equation. Which of the following is not its solution? (a) (6, 0)(b) (4, 0)(c) (2, 3) 4. Is (3, 2) a solution of x + y = 6? 5. Is a solution of 2x + 3y = 12? 6. (i) Write the equation of x-axis. (ii) Write the equation of y-axis. 7. Express in the form of ax + by + c = 0 and write the value of a, b and c. 8. Express 2x = 5 in the form ax + by + c = 0 and find the value of a, b and c. 9. Write two solutions of 3x + y = 8. 10. If x = –1 and y = 2 is a solution of kx + 3y = 7, find the value k.

Answer 1

Answer:

3x-4y+9=0

ax+by+c=o

a=3x, y=-4 and c=9
