Answer: Slope=1
You can find slope by using the 'rise over run' method. Count the number of units along the x axis, and up the y axis. As I can see, I think it is labeled as 4,4. So put the numbers into y/x (4/4) and then simplify as needed. In this case (If I can see correctly) then the slope is 1.
When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,
y=kx
Plug in (5,100)
100=k(5)
K=20
Answer:
27,9
Step-by-step explanation:
x + y =36
x - y = 16
27 + 9 = 36
27 - 9 = 16
What is the last one number 12
When you first look at thius graph, you should notice two things immedietly.
1. This graph will have a positive slope, because the line is going up.
2. the y-intercept is -2 because that's where it is on the y-axis.
Now, you have been given two points, (2, 1) and (0, -2). You can put these two points into the slope formula, which is: m =

=

= 3/2.
So, now you have your slope and your y-intercept. Now, just put them into y = mx + b form!
y = 3/2x - 2 (it is ubtracting two instead of adding two because it is a negative two.)
Hope this helps!!
