Answer:
Step-by-step explanation:
First, find the <em>rate of change</em> [<em>slope</em>]:
Now plug these coordinates into the Slope-Intercept Formula. It does not matter which ordered pair you choose:
4 = −6⁄7[2] + b
−1 5⁄7
_______________________________________________
10 = −6⁄7[−5] + b
4 2⁄7
** You see? I told you it did not matter which ordered pair you choose because you will ALWAYS get the exact same result.

Answer: a package of cookies cost $ 5 and each bag of chips cost $5
Step-by-step explanation:
Let x represent the cost of a package of cookies and y represent the cost of a bap of chips ,then from the first statement :
4x + 4y = 40
dividing through by 4 , we have
x + y = 10 ........................... equation 1
From the second statement
3x + 5y = 40 ..................... equation 2
Solving the system of linear equation by substitution method , from equation 1 , make x the subject of the formula , that is
x = 10 - y ................... equation 3
substitute x = 10 - y into equation 2 , we have :
3 (10 - y ) + 5y = 40
30 - 3y + 5y = 40
30 + 2y = 40
subtract 30 from both sides
2y = 40 -30
2y = 10
y = 5
substitute y = 5 into equation 3 , equation 3 becomes
x = 10 - 5
x = 5
Therefore ; a package of cookies cost $ 5 and each bag of chips cost $5
Answer:q=-81
Step-by-step explanation:6(q-87)=36
6q-522=36
-522 from each side
6q=-486
Divide 6 from each side
q=-81
To write this function in function notation all you would need to do is rearrange the equation for y.
3x + 2y = 12
3x - 3x + 2y = 12 - 3x
2y = 12 - 3x
2y/2 = 12/2 - 3x/2
Y = 6 - 3/2 X or
Y = -3/2 X + 6.
