Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number

Formula :
Base²= Hypotenuse² - Perpendicular ²












Remember the a² in formula has nothing to do with the a we have to find. :)
(0,2)
GRAPH ALL THREE COORDINATES AND DRAW LINES TO SEE WHERE IT INTERSECTS
This one isn't too hard, just plug in each value!
x = -1
y = -4(-1) + 3
y = 7
x = 0
y = -4(0) + 3
y = 3
x = 1
y = -4(1) + 3
y = -1
x = 2
y = -4(2) + 3
y = -5
