27) which answer choice describes the sequence of transformations that could result in triangle a'b'c'? a) a 90° rotation, and a reflection across the y-axis b) a reflection across line p, and a translation 8 units down c) a 180° rotation, and a translation 10 units to the right d) a reflection across line p, and a reflection across the x-axis

Iam trying to solve a linear equation for the shoe size of someone 84" tall taking into consideration example 1 is 69" tall with a shoe size of 9 and example 2 is 72 inches tall with a shoe size of 11. i understand that the equation should be y=mx+b and that on the graph the answer is (3,2) but i just don't understand how to create the equation to solve for 84-inches and 60-inches tall questions. after two days, i need .

Reflect the point (7,0) across the y-axis
