Question

please ....... help me to solve this assignment

Answer 1

for questions like 15 th imagine a mirror on the axis asked in the question like in the first part the points co ordinates are (3,5) and we have to imagine a mirror on the x axis remember if the mirror on on the x axis the value of the x coordinate remains same i.e. no negative sign but the y axis will be -ve hence points will be (3,-5)
similarly for second part when mirror is at y axis for that point the value of y axis will be same but the sign of the x axis value will be -ve i.e. (-4,-2)
in the 16th question just put in 3 values for both x and y that satisfy the equation and then plot those points on graph join the 3 points it will give straight line to get the points.(extend the line on both sides if u have to)
