The answer to this is 19. The reason why is because the median falls between 18 and 20. After that, you have to take the middle number that falls between 18 and 20. In this case, 19.
Answer:
See attachment for graph
Or
The slope intercept form is 
Step-by-step explanation:
Assuming you want to graph the straight line given in point-slope form as
Then we need at least two points on this line
When we compare to the point-slope formula 
then we obtain (-5,-2) as a point on this line so we plot it.
When x=0, y=4(0+5)-2=18 so we plot (0,18)
We then draw a straight line through as shown in the attachment.
On the other hand, if you had wanted the equation slope intercept form, then we expand to obtain:
Answer:
no
Step-by-step explanation:
to determine if (0, 9 ) is a solution substitute x = 0 into the equation and if the result is 9 then it is a solution
y = - 3(0) + 5 = 0 + 5 = 5 ≠ 9
then (0, 9 ) is not a solution to the equation
Answer:
0.87 which is 13/15
Step-by-step explanation:
6/5 becomes 18/15
3/3 becomes 15/15
18/15-15/15 is 13/15
13 divided by 15 is about 0.87
13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8
