Can you help me complete the ordered pairs for the equation?I need help for these ?

Question

y=-7x;(3,?);(?,14)

y = -x +7;(?,2);(7,?)

Answer 1

In each equation,you're given either an x or a y and you need to find the other.

Just plug in what you know into the given equation and solve for your other piece:

y = -7x

where x = 3:

y = -7(3)

y = -21

where y = 14

14 = -7x

x = -2

It's just that simple.  I'll let you do the other one.

Answer 2

y = -7x ....(3, [3*7]) = (3, -21)

...........(?, -7x) = (-2,14)

y = -x +7 .... (?, 2) = (-5,2)

.................(7, 0)
