I give you some hints, please try it. 1st, solve the given two equations you will get values of x  and y,which is passing point of the required line. 2nd, line is equally incline to the axis, so, x-intercept=y-intercept So, a=b Now equation .....

Let the equation of the straight line be x/a + y/b = 1, which meets the x and y axes at A (a, 0) and B (0, b) respectively. The coordinates of the mid-point of AB are (a/2, b/2). Since the point (2, )4 bisects AB, therefore a/2 = 2 .....

Here, to find SI, we need to find rate. For this, Rate=R=12 x 2 paisa per 100 paisa per year                [12 month=1 year] =24% Now time=T=1+8/12=..........year Now SI=PTR/100=....................use .....

To prove it, We have to show, <ABC=<ECD, since they are corresponding angles. Now, x+100=180, linear pair. or, x=80 Now, in triangle,ABC, <ABC+45+80=180 or, <ABC=180-125=55 Here we see thst, <BAC=<ECD=55 So, .....
