Determine whether the ordered pair is a solution of the linear equation y = 11r - 4 (0 -4)

KiRa [710]

Hi there!

»»————-　★　————-««

I believe your answer is:

Yes, it is a solution.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

I am assuming that 'r' is supposed to be 'x'.

⸻⸻⸻⸻

$y=11r-4\\------------\\\rightarrow -4 = 11(0) - 4\\\\\rightarrow -4 = 0 -4\\\\\rightarrow \boxed{-4=-4}$

⸻⸻⸻⸻

The ordered pair is a solution. You can also tell that it is a solution because the equation given is in slope-intercept form, and '-4' is in b's spot.

⸻⸻⸻⸻

$y = mx+b$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Can some help me with this

Bumek [7]

Start from (0, -1) - your first point
Go up three and left two - your second point
Or you can go down 3 and right two
Keep doing that and it will create a linear graph
