2. Seiji and Gavin both worked hard over the summer. Together they earned a total of $425. Gavin earned $25 more than Seiji.
(a) Write a system of equations for the situation. Use s for the amount Seiji earned and g for the amount Gavin earned.
(b) Graph the equations in the system. (I only need help with this!!)
(c) Use your graph to estimate how much each person earned.

Answer 1

s= seiji earnings

g = gavins earnings

a) s+g =425

g = s+25

b) see graph

s = -g +425

s = g-25

these are in the form s = mg+b where we have the slope and the s intercept

s is on the vertical axis and

g is on the horizontal axis

c) they intersect at about (225, 200)
