Ok, so first, the y-intercept is always the last number. So the y-intercept for the first equation would be -1, and for the second equation, 4.
Put a dot, or a point on -1and 4 on the graph.
The slope is always he number with an x.
So the slope would be 3 for the first equation.
And the slope for the 2nd equation would be -2.
If the slope doesn't have a denominator, put 1 as it's denominator.
So, 3x would turn into
And -2x would turn into
So the rule for slope is:
So, go to your -1, and go up 3 and 1 right. Keep doing that until you reach the end of the graph.
Now, go to your -4, go down 2 and go left 1. Keep doing that until you reach the end of the graph.
Now, draw the lines.
I'll show on piece of paper how to do this if you dont get the explanation I gave.
Varies direct means y=kx
6=k*72
so k=1/12
y=kx
y=8/12
y=2/3
The answer would be 347 over 30(347/30) adding all of those together. I hope that helps!!
Answer:
39.5
Step-by-step explanation:
From low to high:
36, 36, 37, 37, 38, 38, 39, 40, 40, 40, 45, 45, 45, 45
Median:
39, 40
(39 + 40)/2
79/2
39.5
4480000. Hope this helps.
