+128631 7....(9,3) , m = 4/9
y - 3 = (4/9)(x - 9)
8..... y = l 10x - 2 l - 7
The parent function is y = l x l
And we can write
y = l 2 (5x - 1) l - 7
y = 2 l 5x - 1 l - 7
( 1/5 , - 7 ), x = 1/5, translated to the right by 1/5 unit amd down 7 units
Here's the graph of the parent and the given function and axis of symmetry :
