What represents a function​ or is there not one

Mathematics
1 answer:
weqwewe [10]3 years ago
4 0

Answer:

Yes it is a function because all the x values are different. If there were two or more of the same number in the x list it would not be a function. And it doesn't matter for the y list if two or more of the numbers are the same.

In slope-intercept form, write the equation of the line that passes through points (-7, 8) and (2, -2).
Ymorist [56]

Answer:

y = -1x + 0.5

Step-by-step explanation:

First, I plotted the points (-7, 8) and (2, -2). Then, I drew a line connecting the two points. At the point (-7, 8), I went down 2 squares and to the right 2. This would give me a slope of -1. Since the line touches the y-axis at 0.5, this is the y-intercept.

I am not sure about the y-intercept of this equation. If I got this wrong, I am sorry and please let me know. Thank you!
