Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5
y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)
y = 4/5x - 3.6 ( y = mx + b formula)
4/5 = 0.8
y = 0.8x - 3.6
x = 1
y = 0.8(1) - 3.6
y = - 2.8
x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2
x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2
x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4
x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4
etc.
graph using the (x,y)
connect the dots
hope this helps
The rate of change:
( y2 - y1 ) / (x2 - x1) = ( 18 in - 12 in ) / ( 6 ft - 4 ft ) =
= 6 in / 2 ft = 3 in / 1 ft
Answer: D ) 3 inches up per foot across
The correct answer is C !
Answer: $10.00
Explanation: round 6.2 down to 6, and round $56.00 up to $60.00 and then see which answer choice fits. 10 multiplied by 6 is 60 which would mean about 1 pound of pecans costs $10.00
