The you find this is by first finding the slope. You do this by finding the difference between both x values and then both y values. You get 12(x), 6(y) then write it as a fraction. it is 12/6 which simplifies to 2. 2 is our slope. then you write it out in slope intercept form (y=mx+b) and plug in your numbers. pick one set of original points an put them in to x and y. now you just solve for b. this gives you -9 as b. you put it together to get
y=2x-9
hope this helps!!!! :)
Step-by-step explanation:
y = 2kx², where k is a real constant.
We have:
2k(1)² - 2k(3)² = 32 or 2k(3)² - 2k(1)² = 32.
=> 2k - 18k = 32 or 18k - 2k = 32
=> -16k = 32 or 16k = 32
=> k = -2 or k = 2.
When x = -2,
y = 2(-2)(-2)² or y = 2(2)(-2)².
=> y = -16 or y = 16.

Answer: x=-5
Step-by-step explanation:
Distribute
6(x+3)-1(x+4)=-11
6x+ 18-1(x+4)=-11
6x +18-x-4=-11
Subtract the numbers
6x +18-x-4=-11
6x +14-x=-11
Combine like terms
6x +14-x=-11
5x +14=-11
subtract 14 from both sides of the equation
5x +14=-11
5x +=14-14 = -11 -14
simplify
5x=-25
divide both sides
x=-5
