yes but we write it x^2 for x squared
yes, constant slope is linear
slope = change in y / change in x
for example
m = (16-7)/(9-3) = 9/6 = 3/2
y = (3/2) x + b
if x = 3, y = 7
so
7 = (3/2)(3) + b
14/2 = 9/2 + b
b = 5/2
so in the end
y = (3/2) x + 5/2
if x = 7
y = (3/2)(7) + 5/2
y = 26/2
y = 13
=================
check a point to be sure
if x =9
y = (3/2)9 + 5/2
y = 27/2 + 5/2 = 32/2 = 16
so my equation is right
To make sure its correct before I turn it in
