Y varies directly with x. If y=25 when x=5, find y when x =-4<br><br>y =​
alina1380 [7]

Answer:

y = -20

Step-by-step explanation:

Given that y varies directly with x it means changing x will also cause change in y

Mathematically it can be written as:

y∝x

Removing the proportionality symbol

y = kx

Given y=25 when x=5 Putting the values

25 = k(5)\\k = \frac{25}{5}\\k = 5

Now

y = 5x

We have to find the value of y when x = -4

Putting x=-4

y = 5(-4)\\y = -20

Hence,,

y = -20

Help pls I’m #######} my teacher gave this to me without knowing nun

Basically, you just move every individual point up, down, left, or right by the amount indicated.

For example, point G is graphed on the point (-3, -1). Moving it right 5 and up 1 will give you G’, which is (2,0)

T is graphed on the point (-1, -1). Moving it right 5 and up 1 will give you T’, which is (4,0)

B is graphed on the point (-3, -5). Moving it right 5 and up 1 will give you B’, which is

(2,4)
