How do write a line with point (7,9) and a slope of 1 in slope intercept form?

Mathematics
1 answer:
Katarina [22]2 years ago
3 0

Answer:

9 = 1(7) + 2

So generally it is:

y = x + 2  (I think this is the answer your teacher wants)

Step-by-step explanation:

y = mx + b is the slope intercept form equation

you know that 9 is one of your y points, so you can plug it in (9 = mx + b)

you also know that 7 is an x point, so you can plug it in as well (9 = m(7) + b)

then you can plug in your slope because you know that as well (9 = 1(7) + b)

to find your intercept, subtract your y point from the x point since there is a slope of one (you can only do this for a slope of one) you will get two as your intercept (9 = 1(7) + 2) this is your exact equation with that one point, but to generalize it so you could find any point, you would write: y = x + 2 (you don't include the slope because it is just one)

Hope this helped!

An arithmetic sequence is defined by the general term tn = -5 + (n - 1)78, where n ∈N and n ≥ 1. What is the recursive formula o
Gnoma [55]

Answer:

C

Step-by-step explanation:

In general for arithmetic sequences, recursive formulas are of the form

aₙ = aₙ₋₁ + d,

and the explicit formula (like tₙ in your problem), are of the form

aₙ = a₁ + (n - 1)d,

where d is the common difference. So converting between the two of these isn't so bad. In this case, your problem wants you to have an idea of what t₁ is (well, every answer says it's -5, so there you are) and what tₙ₊₁ is. Using the formulas above and your given tₙ = -5 + (n - 1)78, we can see that the common difference is 78, so no matter what we get ourselves into, the constant being added on at the end should be 78. That automatically throws out answer choice D.

But to narrow it down between the rest of them, you want to use the general form for the recursive formula and substitute (n + 1) for every instance of n. This will let you find tₙ₊₁ to match the requirements of your answer choices. So

tₙ₊₁ = t₍ₙ₊₁₎₋₁ + d ... Simplify the subscript

tₙ₊₁ = tₙ + d

Therefore, your formula for tₙ₊₁ = tₙ + 78, which is answer choice C.

Why might you want to use the commutative property to change the order of the integers in the following sum before adding
Delicious77 [7]
<span>Commutative Property is the property in which you can move around numbers in numerical operations like, addition and multiplication while retaining their result. In contrast to subtraction and division in which position is an important factor for every result, here it is regardless. </span>Why might you want to use this property?<span>Well, most importantly it suits the operation of addition and hence, to ensure the arrangement of the number is in symmetric proportion to its counterpart such as 3 + 2=2 + 3. Or rather, understanding that the equations in both sides are but the same and equal in sum. Thus, this is much more usable or will make more sense if used in a larger scale of complex equations and integers.<span>
