Answer:

1. C = $100 = .25(m)

2. C = $150

3. 800 = m

Step-by-step explanation:

1. C = $100 (flat fee rate) + .25m

2. c = $100 + .25(200 miles)

↓

c = $100 + 50

↓

c = 150

3. 300 = 100 + .25(m)

-100 -100 (subtract on both sides)

--------------------------------

200 = .25(m)

------------------- (divide by .25 to get m by itself)

.25

Therefore being 800 = m

What is the slope of the line 3 + 4x = 2y - 9

SSSSS [86.1K]

Hello!

Ok so ideally we would like to see this in y=mx+b form. But it will take some algebreic skills to ninja our way through this.

I'll show my steps so you can follow,

3+4x = 2y - 9 (original equation)

Next we just add 9 to both sides,

12 + 4x = 2y, now we can divide both sides by 2,

y=2x+6 as our final equation. This is in y=mx+b form, thus the slope of our line is 2 because the 2 is sitting in the m space of the equation. If you still dont understand linear stuff, I'd google slope-intercept form

Hope this helped!
