Answer:
16
Step-by-step explanation:
These are known as simultaneous equations,,
2x + y= -3 take this as 1st equation
x-2y=-4 take this as 2 nd equation
therefore x - 2y= -2 should be multiplied by 2 inorder to cut off 2x and 2x from the first and second equations.
by multiplying we get 2x - 4y = -4
therefore 3rd equation should be substracted from 1st equation...
now, 2x -4y - 2x -y = -4-(-3)
therefore, -2x and +2x is cut.
as a result -5y= -1
therefore y = 1 /5
then let us find x
2x + y = -3
::: 2x + 1/5= -3
therefore 2x= -3-1/5
finally, x= -16/5÷2
then x= 8/5

join for your answer and ask
694
you just subtract 1212 by 518
694+518=1212
The slope is 3/4 .
Hope this helps!!
