Solve graphically y = 2x - 6 and y = -2x + 10. Write down the co-ordinates of the point of intersection of the two lines

Question

amistre64 · Answer

this site really isnt designed to draw a graph on ..

anonymous · Answer

i really just need help finding the coordinates so i can graph it

amistre64 · Answer

im curious as to whether the y component is centered between you intercepts :)

anonymous · Answer

set the lines equal and solve 
$$2x-6=-2x+10$$

amistre64 · Answer

plug a point at -6 and slope up 2 right 1 and connect the dots

anonymous · Answer

$$4x=16$$
$$x=4$$ and since 
$$x=4$$ then 
$$y=2\times 4-6=2$$

amistre64 · Answer

y should be 2 if i see it right :)

amistre64 · Answer

yep ... i sawed it right lol

anonymous · Answer

lol sweet thanks

anonymous · Answer

to find the points of intersection, set the equations equal to each other.

$$2x -6 = -2x + 10$$
$$4x = 16$$
x= 4

Then plug in the x coordinate to one of the equations.

y= 2(4) -6 = 2


The point is ( 4. 2)

anonymous · Answer

wolfram is nice, but to solve 
$$2x-6=-2x+10$$ rather unnecessary
