First, create the equation that models the situation.
The amount Anne already saves is the intial value, ory-intercept, which in this case is 125. She adds 2 to her savings everyday/ so the rate of change, or slope, is 2.
y=125+2x or y=2x+125
plot the y intercept then plot a second point using the slope of 2 or 2/1 draw a line that connects the y intercept and the other point.
We can assume that the y-intercept for this equation is 125, because that would be how much Anna already has saved before she begins saving money from her allowance. Then, we know that Anna adds $2 to her savings each day from the problem, so we know that the slope will be positive 2 then.
