Answer 1

1: Solve the equation for y.

4x – 5y = 9

i got y = 4/5x - 9/5

Answer 2

2: Which ordered pair in the form (a, b) is a solution of this equation?

4a – 5b = 24


A.
(–5, –2)

B.
(6, 0)

C.
(0, 6)

D.
(–2, –5)
i got (6,0)

Answer 3

3:Which points have opposite x- and y-coordinates [for example, (2, –2) or (–3, 3)]? (Hint: Some answers may have some, but not all points that name opposites. Choose the answer that contains only points that have opposite x- and y-coordinates for each point named.)

A.
D, Z

B.
D, L

C.
Z, L

D.
C, D, Z

I got B

Answer 4

#1

\(\sf 4x - 5y = 9\)

Subtract 4x to both sides:

\(\sf -5y = -4x + 9\)

Divide -5 to both sides:

\(\sf y = \dfrac{4}{5}x - \dfrac{9}{5}\)

Answer 5

okay

Answer 6

4:Which point is the graph of the ordered pair (2, –4)?

A.
point A

B.
point B

C.
point C

D.
point D

i got point b

Answer 7

#2

\(\sf 4a – 5b = 24\)

\(\sf (6, 0)\)

Plug in what we know:

\(\sf 4(6) – 5(0) = 24\)

Multiply:

\(\sf 24 – 0 = 24\)

\(\sf 24 = 24\)
