Question

Find the value of y when x= 7.
y=-4x

Answer 1

Y= -4x
First enter in the 7 as X
Y = -4 (7)
You will then multiply -4 • 7 [the “•” is another way or saying multiply just use it so you won’t get the symbol and X confused]

Once you have multiples the answer will be

Y = -28

Answer 2

y = -28

Explanation:

y=-4x

Let x=7

y = -4*7

y = -28
