Let the points be (p,q) and (r,s).
The slope is (s-q)/(r-p). The equation is y-s=(s-q)(x-r)/(r-p).
This can be written (y-s)(r-p)=(s-q)(x-r).
y(r-p)-s(r-p)=x(s-q)-r(s-q); y(r-p)=x(s-q)+rs-ps-rs+qr; y=x(s-q)/(r-p)+(qr-ps)/(r-p).
Note that r cannot be equal to p in this standard form. If r=p we have a vertical line x=p.
If q=s we have the horizontal line y=q.

Answer: Part A - C, Part B - 12 pieces

Step-by-step explanation:

<u>Part A:</u>

We know that 1/4 of Meredith's sub is bigger than 1/4 of Jim's sub, so we can set up an inequality.

Let Meredith's sub size = m; Jim's = j

Therefore, 1/4*m > 1/4*j

We can multiply both sides by 4:

m > j

Thus, the correct answer is C

<u>Part B:</u>

Since he had 1/4 of it left, that means he at 1 - 1/4 of it = 3/4 of his sub.

We can calculate the value of 3/4 * 16 = 12 pieces

Answer:

a = −bx+7x−4 over x


Step-by-step explanation:

solve for a:

7+ax−5x=3+2x−bx

add 5x to both sides:

ax−5x+7+5x=−bx+2x+3+5x

ax+7=−bx+7x+3

add -7 to both sides:

ax+7+−7=−bx+7x+3+−7

−bx+7x−4

lastly divide both sides by x.
