Answer:
(-1,-5)
Step-by-step explanation:
y = 7x + 2
y = -4x – 9
Since both equations are equal to y, we can set them equal to each other
7x+2 = -4x-9
Add 4x to each side
7x+2+4x = -4x+4x-9
11x+2 = -9
Subtract 2 from each side
11x+2-2 = -9 -2
11x = -11
Divide each side by 11
11x/11 = -11/11
x = -1
Now we need to find y
y = 7x+2
y = 7(-1)+2
= -7+2
=-5
Answer:
y-2 = 7x
y-9 =4x
We can try an average here
y-6 = 5.5x
if y = 11-6 then y= 5 and x =1
Step-by-step explanation:
We then count the subtractions +- - and - - in such order makes both -1 and -5
