Answer:

<u>The "40" represents the flat fee</u> (for an initial consultation)<u>.</u>

Step-by-step explanation:

The equation is in slope-intercept form, y=mx+b, where the mx is the <u>rate of change</u> and the b is like the <u>flat fee, or the base amount</u>.

I hope that helps! :)

leontyne sings for $1,000 an hour. Her rate increases by 50 percent after midnight. If she sings one night from 8:30 pm until 1:
iren2701 [21]
From 8.30 pm to 12 : 00

Difference = 12 : 00 - 08:30 = 3 : 30

3 hours 30 minutes = 3.5 hours.

Total for those hours = 3.5 * 1000 = $3500

From 12:00 to 1:00 am  = 1 hour.

50% increase =  50% of 1000 = .50 * 1000 = 500

So it will increase to 1000 + 500 = $1500 per hour.

For the 1 hour extra, 1 * 1500 = $1500

Total = $3500 + $1500 = $5000

She will be paid $5000

Which is the slope of the graph of the equation below? X - y = 5
icang [17]

First, make it into slope intercept form. Subtract x form both sides

x (-x) - y = 5 (-x)

-y = -x + 5

Isolate the y. Divide -1 from both sides

(-y)/-1 = (-x + 5)/-1

y = x - 5

The slope in the form: y = mx + b, is m, which is next to the x

In this case, the m is 1

You're slope is 1

hope this helps
