Answer to Question #12658 in Analytic Geometry for RYAN
What is the common point between lines y = -x + 7 and y = 3x + 10?
To find common point we should equate the expressions in the right parts:
& -x + 7 = 3x + 10
+x & +x
Corresponding value of y we can find by substituting obtained x=-3/4 into any of the equations:
