Unit 1
The points on a graph start at 3,4 but where translated 3 units up and 6 units right. Where is the point located at now?
9,7
(TRUE/FALSE) if the x's repeat its a function
false
(TRUE/FALSE) Slope is rise over run
true
what is the solution for intersecting lines?
(x,y)
simplify the polynomial
