<PRE><B>Question 1168907</B>
This is y=2x+25
it comes from inspection (intercept is when x=0 and y=25, and the slope is 2)
or point-slope formula y-y1=m(x-x1), m slope, (x1 y1) a point
any 2 points (0, 25) and (2, 29)--slope is 4/2=2
y-25=2(x-0)
y=2x+25
dependent and independent variables are a s you described.
Linear relationship because constant. Every 2 brownies increases money $4.
unit rate is $2, the slope of the line.
Starting point is (0, 25)
