the answer of this question is postive
Step 1: Find the slope using
:
![m= \dfrac{1-(-2)}{4-(-2)} = \dfrac{3}{6} = \dfrac{1}{2}](https://tex.z-dn.net/?f=m%3D%20%20%5Cdfrac%7B1-%28-2%29%7D%7B4-%28-2%29%7D%20%3D%20%5Cdfrac%7B3%7D%7B6%7D%20%3D%20%5Cdfrac%7B1%7D%7B2%7D)
Step 2: Plug the slope and one-point into point-slope form
:
Let's use (4,1) since there's no negative involved. That makes it easier:
![y-1 = \frac{1}{2}(x-4)](https://tex.z-dn.net/?f=y-1%20%3D%20%5Cfrac%7B1%7D%7B2%7D%28x-4%29)
Here is some pro tips, I take algebra 1, and I’m in middle school too.
x * x = x^2
If you see anything like (x + 5)(x - 5), solve using FOIL, (front, outer, inner, last), it’s basically the distributive property for four numbers and x’es.
Distributive property is a must know.
And also, if you are feeling nervous, remember, even if you fail the leap test, it doesn’t make you less of a intelligent, kind, and caring person.
Answer:
no
Step-by-step explanation:
this "line" does not pass the vertical line test, meaning there are some x points with multiple y's
if a line has x points with multiple y's, it is not a function
