Find the slope of the line that contains the points (-9, -3) and (-19, -3).
NNADVOKAT [17]

Answer:

Slope (m) = 0

Step-by-step explanation:

We will use this formula to find the slope⤵⤵⤵

\frac{y _{2} - y _{1}  }{x _{2} - x _{1}  }

(Sorry if it's a bit small btw)

Now we plug in the values accordingly:

-3 - (-3) = -3 + 3 = 0

-19 - (-9) = -19 + 9 = -10

Slope = 0/-10

So we have 0/-10, which means our slope is actually just 0.

(This also means that the line on the graph will be horizontal.)

Hope this helps you :)

Answer:

  • See below

Step-by-step explanation:

Let the amount charged is y and number of hours is x.

Then the equations are as below.

<u>Attorney A:</u>

  • y = 150x + 250

<u>Attorney B:</u>

  • y = 175x + 150

<u>If the amounts are equal, then:</u>

  • 150x + 250 = 175x + 150
  • 175x - 150x = 250 - 150
  • 25x = 100
  • x = 4 hours
