What is the value of y in the following system of equations?

y = x - 10

y = 2x + 5

Question 2 options:

25

-15

-25

15

-25

Step-by-step explanation:

make both equal

x-10=2x+5

add

-2x+x=10+5

-x=15

x=-15

solve for Y

y=x-10

y=-15-10

y=-25

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
