Question

HOW PLEASE EXPLAIN TOO WITH ANSWER

Answer 1

Answer:

y = -2x + 3

Step-by-step explanation:

5 x -2 + 3 = -7

3 x -2 + 3 = -7

9 x -2 + 3 = 1

-3 x -2 + 3 = 9

You just have to test all of the options, everything, out and pick what fits.

Hope that helps!

Answer 2

The answer is the second question: y=-2x+3.

Explanation:

You will have to try to substitute the numbers shown in the table with the 4 equations. And see which equation satisfies all the expressions in the table.

y = -2x + 3

Sub x = 5 and y = -7,
-7 = -2(5) + 3
-7 = -10 + 3
-7 = -7
(x=5 and y=-6 satisfies the equation y=-2x+3)

Sub x=3 and y=-3,
-3 = -2(3) + 3
-3 = -6 + 3
-3 = -3
(x=3 and y=-3 also satisfies the equation y=-2x+3)


Same goes for all the other numbers...

Hope it helps :)
