The slope of this trend line is m = (0-28) / (14-0) = -2. The y-intercept can be read directly from the graph: It is 28. Thus, the equation of this trend line is k = -2J + 28.
Answer:
The first one. The single line
Step-by-step explanation:
I can explain later but since you need it quick I will send my answer now :3
Further explanation:
A function is only a function if there are two x values to a single y value.
You can use the "vertical line test" to find out if a function is a function or not.
The vertical line test is where you put a line vertically through the function.
If at any point along the vertical line the function touches the line more than once, then it is not a function.
Answer:
We can tell by the graph that it has a positive slope. The
y-intercept is at positive 4. Trying to find the next whole number intercept point will be at (-2,0). Count up and over from that point to the y-intercept point, and put it in rise over run form... 5/2 (up 5, over 2). Now apply these known variables into the slope intercept form: y = mx + b.
The final answer is: y = (5/2)x + 5
M is the slope and B is the y-intercept.
-5 and -4 is -9 that’s correct
