Question

Complete the following ordered pairs. Y=-7x+8 (0,__) (7,__) (__,36)

Answer 1

Answer:

Answers are in bold in explanation

Step-by-step explanation:

We are given the equation:

y = -7x + 8

The first x value is 0

y = -7(0) + 8

y = 8

(0, 8)

The next x value is 7

y = -7(7) + 8

y = -41

(7, -41)

Now we are given the Y value instead of X, so we do this:

36 = -7x + 8

Subtract 8 on both sides to leave -7x alone

28 = -7x

Divide by -7 on both sides to isolate x

-4 = x

(-4, 36)

Answer 2

Answer:

(0,8) (7,-41) (-4,36)

Step-by-step explanation:

y = -7x + 8

y = -7(0) + 8

y = 8

(0,8)

y = -7(7) + 8

y = -49 + 8

y = -41

(7,-41)

(36) = -7x + 8

-7x = 28

x = -4

(-4,36)
