1)In the figure, the vertices of right-angled isosceles triangle ABC are A, B(2,0) and C(8,0) respectively. find the equations of AB and AC

2)If the x-intercept and y-intercept of the straight line L: B(y-2) =Ax+8 are -8 and 3 respectively, find

a)the value of A and B

b)the slope of the straight line L.
