Answer:
y = 3x - 9
Step-by-step explanation:
We first need to find the slope (m)
m = =
=
= 3
y = mx + b
y = 3x + b
(4, 3)
y = 3x + b
3 = 3(4) + b
3 = 12 + b
-12 -12
-9 = b
(1, –6)
y = 3x + b
-6 = 3(1) + b
-6 = 3 + b
-3 -3
-9 = b
y = 3x - 9
To check: (1, –6)
y = 3x - 9
-6 = 3(1) - 9
-6 = 3 - 9
-6 = -6
Hope this helps!
Answer:
<em>Kaya found 25 shells on the beach yesterday.Today she found 25 more shell. She sorted all the shells into 5 pile.Which equation can be used to find how many shells are in each pile? </em>
<em>A.s=(25+25)÷5 </em>
<em>B.s=25÷5 </em>
<em>C.s=(25+25)-5</em>
Equation A can be used to find the number of shells in each piles.
Step-by-step explanation:
Given:
Number of shells Kaya found day before =
Number of shells she found today =
According to the question:
She sorted it into piles meaning we have to equally put them in each pile, for this we have to divide the total number of shells.
Let the number of shells in each pile =
And total number of shells =
So,
The number of shells in each pile.
⇒
⇒
⇒
From equation where,
gives the same answer.
Then option A is the right choice.
