3(x+4) = 2x +4x - 6
x = 6
can you find the slope of a non-linear line
(not a straight line)
Why or why not
no you cannot because it does not have a constant and there is no pattern to determine y value for x input
graph this equation
y = 1/4x -2
y intercept is -2
slope is up 1 right 4
create a story with a y intercept of 50 and a slope of -10
anything where you start at 50 and lose 10 per movement

6(e+ 42 ) -12 = 6e + 84
infinite
same variable
same constant
