If the two lines 2x + y= 0 and y=3 are plotted on a typical xy coordinate grid, at which point will they intersect?Can someone point me in the direction of a vidoe to show how this is done

Answers

we have
equation 1   2x+y=0

equation 2  y=3

substitute the equation 2 in equation 1
2x+[3]=0 \n 2x=-3 \n x=- (3)/(2)

the solution is the point
(- (3)/(2) ,3)

using a graph tool
see the attached figure

2x + y = 0
2x + 3 = 0
      - 3  - 3
      2x = -3
       2      2
         x = -1¹/₂
(x, y) = (-1¹/₂, 3)
