Change in y over change in x
Step-by-step explanation:
To make this easier to understand lets make a table
<u> x | y </u>
1 | 2
2 | 4
3 | 6
Now we go back and find the slope. This is really simple as the rise and run is displayed.
- Count the change in x
In this case x changes by 1
2. Count the change in y
In this case it changes by 2
Now put it into rise over run
Rise(y)/Run(x)
your m or slope would be 2/1 or 2
and in a y=mx+b would be
y=2x+b
Answer: green shirts = 6
Blue shirts = 11
Yellow shirts = 4
Red shirts = 7
Step-by-step explanation:
Red shirts = 7
Let green shirts be x.
There are 5 more blue shirts than green shirts. This means:
Blue shirts = x + 5
There are 2 fewer yellow shirts than green shirts. This means:
Yellow shirts = x - 2
There are 28 shirts in total
Red + blue + yellow + green = 28
7 + (x + 5) + (x - 2) + x = 28
7 + x + 5 + x - 2 + x = 28
10 + 3x = 28
3x = 28 - 10
3x = 18
x = 18/3
x = 6
There are 6 green shirts
Blue shirts = x + 5 = 6 + 5 = 11
Yellow shirts = x - 2 = 6 - 2 = 4
Red shirts = 7

there is no change at all so you do not save anything.
