im so sorry but i need math help im sorry please regarding ordered pairs..?

Question

x-3y=-7;(?,3),(-10,?)


the first ordered pair is (?,3)


the second ordered pair is (-10,?)

complete each ordered pair so that it is a solution of the given linear equation

Answer 1

x-3y=-7
x-3(3) = -7
x-9 = -7
x=2 so first ordered pair is (2,3)

x-3y = -7
-10 -3y = -7
-3y =3
y= -1 so 2nd ordered pair is (-10,-1)

Answer 2

x-3y=-7;(?,3),(-10,?)

Ordered pairs are x,y so you substitute the known value to find the unknown value

x-3y = -7
x -3(3) = -7
x -9 = -7
x=2
pair is (2,3)

Second one
x- 3y = -7
-10 -3y = -7
-3 = 3y
-1 = y
pair is (-10, -1)

Answer 3

use the coordinate they gave you, plug it in and solve
for (?,3) x - 3 * 3 = -7, x = 2
for (-10,?) -10 -3y=-7
-3y = 3
y=-1

Answer 4

so you plug in the numbers...
y=1/3x+7/3
3=1/3x+7/3
2/3=1/3x
x=2
(2,3)

second one:
y=1/3x+7/3
y=1/3(-10) +7/3
y= -1
(-10,-1)
