Answer:
y = 4x + 7
Step-by-step explanation:
parallel = same slope
y = 4x + b
plug in (-4, -9)
-9 = 4(-4) + b
-9 = -16 + b
b = 7
y = 4x + 7
Answer:
7=4x+7
Step-by-step explanation:
To do this you would just plug in (-4,-9) into the equation y=mx+b so we would get -9=4(-4)+b when you simplify you will get -9=-16+b so we would add 16 to both sides and we would get 7=b so we would know that the y intercept is 7 and we know that if a line is parallel to another line is just has a different b so for our equation we would get 7=4x+7

Step-by-step explanation:
Given that the manufacturer of cans of salted mixed nuts state that the ratio of peanuts to other nuts is 4 to 3.
So, ratio of peanuts to other nuts in a can = 4 : 3
Total number of nuts in a can = 464 nuts (i)
We need to find number of other nuts in a can.
Let number of peanuts be 4 k where k is a natural number.
Let number of other nuts be 3 k where k is a natural number.
Total number of nuts = 4 k + 3 k = 7 k (ii)
From (i) and (ii), we get 7 k = 464 which implies
So, number of other nuts in a can = ( approx. )
