Hi!
To solve this, we must make an equation in y = mx + b form, where m is the slope and b is the y-intercept.
Since we are looking at a graph with points, it saves us a TON of work, and all we have to do is simply look at the graph. We only need to find m and b, that's it!
M is the slope, and the slope can be represented by the change between points on a line, also known as <em>rise/run. </em>
If we start at point (-4, -1), and go to point (-2, 0), we can see that it goes up 1 and right 2, which would be represented as 1/2.
B is the y-intercept, and that is simply the point that is on the y-axis, which is the point (0, 1), so our number would be 1.
Therefore, plugging these numbers into the equation, our equation is y = <em>1/2</em>x + <em>1</em>

Hope this helps! :D
I'm not sure about the answer, but this is how I would do it, since 15% and $150 are the same based on the question. do let me know if it's right! :)
There is 360* in a circle, so you would divide 360 by 20 to get 18.
Answer:
Domain (b) = {0, 1, 2, 3, 4....}
Set of all whole numbers
Step-by-step explanation:
Given: A box of pencils costs $10.
Total cost (c) = 10b, where "b" is the number of boxes.
Here c represents the range which is dependent variable and b represents the number of boxes which is independent variable.
For instance, if you buy 10 boxes of pencils, you need to pay = 10(10) = $100
Here we replace b with the number of boxes.
The number of boxes cannot be negative. It will star from 0,1, 2, 3....
Therefore, domain (b) = {0, 1, 2, 3, 4....} which is set of whole numbers.
3.8 / 1.9 = x / 7.6....3,8 miles to 1.9 miles = x miles to 7.6 miles
cross multiply
(1.9)(x) = (3.8)(7.6)
1.9x = 28.88
x = 28.88 / 1.9
x = 15.2 <== Cameron ran 15.2 miles
