Answer:
its the third one. just multiply every number by 1.5 not that hard
Step-by-step explanation:
A) You would use the two points that are closest to the graphed line
(2,7) and (8,13)
B) Slope = change in Y over the change in X:
Slope = (13-7) / (8-2) = 6/6 = 1
Slope = 1
c) Point slope is written as y -y1 = m(x-x1) where m is the slope y1 is the first Y value and x1 is the first x value.
Equation is: y-7 = x-2
d) To rewrite y -7 = x-2 in slope intercept form, you need to isolate y.
To isolate Y add 7 to both sides:
y = x +5

Answer:
5. A.
6. F
Step-by-step explanation:
5. Perpendicular lines have slopes that are negative reciprocals of one another, so slope is 3
y = 3x + b
using coordinates (-6,3)
3 = 3(-6) + b
b = 21
y = 3x + 21
6. I think F is the right answer
N + (n + 2) + (n + 4) = 60
<span>3n + 6 = 60 </span>
<span>3n = 54 </span>
<span>n = 18 </span>
<span>Therefore </span>
<span>youngest daughter's age n = 18 </span>
<span>middle daughter's age n + 2 = 20 </span>
<span>oldest daughter's age n + 4 = 22</span>
