What do you mean? If you want it in order than you can say it. -17, -10.5, -4, 2.5, 9
<span>Write 7.4 as a mixed number and as an improper fraction. Do not try to simplify your answers.

The answer is 37/5
The answer should be n= -6
<span>1. Make y the subject
a) 4y=12x+18
y = 3x + 4.5
b) 2x=7-3y
3y = -2x + 7
y = -2/3x + 7/3
2.
a) what is the equation of the line which passes through both (-2,-4) and (6,16)
slope = (16 + 4)/(6 +2) = 20/8 = 2.5
y = mx + b
-4 =2.5(-2) +b
-4 = -5 +b
b = 1
equation
y = 2.5x + 1
b) what is the equation of the line perpendicular to y= 1/2X + 7 passing through point (3,9)
</span>y= 1/2X + 7
slope = 1/2
slope of line perpendicular = -2
passing through point (3,9)
y = mx + b
9 = -2 (3) + b
b = 15
equation
y = -2x + 15
Answer:
line c
Step-by-step explanation:
The graph representing a direct variation equation always passes through the origin. This could be graphs (a) or (c)
given y = 
x
with slope =
Since graph (a) slopes down from left to right it's slope is negative
Hence it is not graph (a) as the slope given in the equation is positive.
Hence the required graph is (c)
