(7, 3) slope = 4/7
The equation is
y - y coordinate of point = slope (x - x coordinate of point )
y - 3 = (4/7) ( x - 7)
Look at the second one carefully, NSS
To find the first translation....we can solve this for x
8x - 2 = 0
8x = 2
x = 2/8 = 1/4 ⇒ means 1/4 units to the right
To find the second translation....... -7 means 7 units down
So.....the vertex is (1/4, -7) translated 1/4 units to the right and 7 units down
Here's the parent graph and the translated graph :
