Question 536929
If the line defined by the equation -4x+2y=8 crosses another line with the equation y=(2/3)x+b at the point (3,a), what is the value of b?
------------
If (3,a) satisfies both equations you get:
-12+2a = 8
a = 2 + b
---
Substitute for "a" and solve for "b":
-12 + 2(2+b) = 8
2+b = 10
b = 8
