Answer:
step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.
step 2. parallel lines have the same slope so the slope is -4.
step 3. y - (-5) = -4(x - (-4)).
step 4. y + 5 = -4x - 16.
step 5. y = -4x - 21.
2 5/7 as a decimal is approximately 2.70
We know that the ones place will be a two. That doesn’t change when you convert. Next you need to divide 100 by 7, which equals 14. Then you need to do 14 times 5, which equals 70. So, now you know the values after the decimal point (.70). Combine that with the whole number 2 to get 2.70.

Factoring x2-45x+324
The first term is, <span> x2 </span> its coefficient is 1 .
The middle term is, -45x its coefficient is -45 .
The last term, "the constant", is +324
Step-1 : Multiply the coefficient of the first term by the constant <span> 1 • 324 = 324</span>
Step-2 : Find two factors of 324 whose sum equals the coefficient of the middle term, which is -45 .
<span> -324 + -1 = -325 -162 + -2 = -164 -108 + -3 = -111 -81 + -4 = -85 -54 + -6 = -60 -36 + -9 = -45 That's it</span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -36 and -9
x2 - 36x - 9x - 324
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-36)
Add up the last 2 terms, pulling out common factors :
9 • (x-36)
Step-5 : Add up the four terms of step 4 :
(x-9) • (x-36)
Which is the desired factorization
Equation at the end of step 1 :<span> (x - 9) • (x - 36) = 0
