Question

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)

Answer 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...

Answer 2

do you know how to solve this one?

Answer 3

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?
