Solve the system y = –x + 6 and y = x – 8 by using graph paper or graphing technology. (1.5 , –6.5) (2 , 2) (10 , 2) (7 , –1)
Well plot the graph by giving some values for x in the two equations and plot them on the same graph..The intersecting points are the answers...
do you know how to solve this one?
you can plot them, and check your answer by solving them. y = –x + 6 y = x – 8 ------------ can you add them to eliminate x, then solve for y?
