Answer:
y=-4x+19
Step-by-step explanation:
Plug into point-slope formula
y-y1=m(x-x1)
y-(-1)=-4(x-5)
y+1=-4x+20
-1 -1
y=-4x+19
Answer:
7 inches
Step-by-step explanation:
First you have to find the average height of each class.
4th Grade:
56, 47, 54, 51, 53, 58, 48, 54, 46, 53
Then you have add it all up and divide it by how many students there are.
56 + 47 + 54 + 51 + 53 + 58 + 48 + 54 + 46 + 53 = 520
520 ➗10= 52
Same process for the 7th Grade.
You end up getting 52 and 59. You then Subtract it to get the answer to the question.
52 - 59= 7 inches
