Question 1062053: at what point do y=.4x+-2.4 and y=-1x+6 intersect
Answer by math_helper(2461)   (Show Source):
You can put this solution on YOUR website! They intersect when the x and y values match. Setting the two functions equal to each other fixes the y value, then we can solve for x:
y = 0.4x-2.4 = -x + 6
1.4x = 8.4
x = 6
y = 0.4(6) - 2.4 = 2.4 - 2.4 = 0 so (6,0) is where they intersect.

Ans: The two lines intersect at (6,0)

Check: Plug x=6 into the other function, just to be sure it produces y=0:
y = -6+6 = 0 (ok)
