Question

X + 5y = -2 2x + y = 5 The point of intersection of the lines has a y-coordinate of _____. 1 3 -1

Answer 1

Y = -1

hope this helps

Answer 2

Y =-1

Explanation:

There is an easy way to find the answer. Basically you want x + 5y = -2 and then you subtract that from 2x + y = 5. What can you do to one of these equations so that when you add them together they will get rid of the x so you just have the y period so the way I did it was double the 2x plus 5y period so now we have 2X plus 10y equals -4. Subtract that from 2x plus y equals 5. The answer is -9y = 9 so y = -1
