Question

helpp

anonymous · Answer

i am going to assume that it is 
$$y=2x-4\y--\frac{1}{2}x+1$$ am i right?

anonymous · Answer

yes

anonymous · Answer

rather 
$$y=2x-4\y=-\frac{1}{2}x+1$$

anonymous · Answer

since $y=y$ you can write 
$$2x-4=-\frac{1}{2}x+1$$ and solve for $x$

anonymous · Answer

if the fraction annoys you, multiply by 2 and get 
$$4x-8=-x+2$$ maybe that makes it easier

anonymous · Answer

huh? im trying to get points for x and y

anonymous · Answer

..... can you explain again please

anonymous · Answer

first find x
then find y

Let x = 0 and 1 in each equation, and find y. Fill in the tables below the equations. 
This will give you two (x, y) points for each equation. Then plot the two lines, and see where they intersect. that point is the solution. To check, test the point of intersection in both original equations to make sure it makes them true.
