She could switch them around by grouping them into groups of 4s, 3s, 2s, or 5s.
Answer:
For (2, 8) the slope is 2
For (-4, -4) the slope is -4
Step-by-step explanation:
The slope is the x axis which goes first
and the y intercept would be the y axis which goes second
Slope goes before the y intercept
for example: (8, 4) the slope is 8 the y intercept is 4

Answer:
y =
and x = 
Step-by-step explanation:
To solve simultaneous equations, you need to have the number in front of both x's or y's the same. (signs doesn't matter)
To get -x to -10x we simply need to multiply the first equation by 10:
-x * 10 = -10x
-9y * 10 = -90y
16 * 10 = 160
-10x - 90y = 160
Now we can add the two equations:
-10x + 10x = 0
-90y + 20y = -70y
160 + 20 = 180
-70y = 180
70y = -180
7y = -18
y = 
Now plug
into the second equation:
10x + 20(
) = 20
10x -
= 20
Move the
over to the other side, making it a positive:
10x = 20 + 
10x = 
Divide both sides by 10:
x = 
So y =
and x =
