Answer:
13)
Line A - slope/constant of proportionality = 5/2
Line B - slope/constant of proportionality = 2/3
14)
unit rate = 3/2 or 1.5
The unit rate, 3/2, is greater than line B's unit rate but is less than line A's unit rate.
Step-by-step explanation:
To find the constant of proportionality for question 13 you use the graph. k = y/x so you find the point at (4, 10) and you go up 10 (y) and over 4 (x). So now you have 10/4 and then you simplify to 5/2. Use the same method for line B to find the slope. Now for question 14 you subtract 10 - 5 to get 5 which is your x and 15- 7.5 to get 7.5 which is the y. So this is now 7.5/5 (y/x) or 3/2. 3/2 is less than 5/2 and greater than 2/3.
Thank you so much!!! Hope this helps!!!
Answer:

Step-by-step explanation:

Take 4 common first,

Since we need 16 outside the bracket, multiplying and dividing by 4,


Simplifying all the fractions,


Answer:
y = - 4
Step-by-step explanation:
x = - 1 is the equation of a vertical line parallel to the y- axis
The equation of a line perpendicular to it will therefore be a horizontal line parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (8, - 4 ) with y- coordinate - 4 , then
y = - 4 ← equation of perpendicular line
Answer:
its just 16
Step-by-step explanation:
Absoulte value is a whole postive form of a number meaning that 16 is the only answer.
