Question

Can someone help me with these problems? I'm in k12 and this assignment was in classkick, so if anyone already completed this and can help, please do. I also am going to be asking some more questions, if you can help with those too. Thanks! (Will give brainliest.)

Answer 1

Answer:

See the explanation

Step-by-step explanation:

Given function

$Y=3x+1$

We need to find $y$ value corresponding to each $x$ value.

So, plug each $x$ value in equation we get,

$plug\ x=4\\y=3(4)+1\\y=12+1\\y=13\\\\plug\ x=6\\y=3(6)+1\\y=18+1\\y=19\\\\plug\ x=10\\y=3(10)+1\\y=30+1\\y=31$

Now in next part of question it ask us to check each ordered pair.

Let us plug each $x$ value and $y$ value in the function $y=-3x-5$

$plug\ (1,-8)\\-8=-3(1)-5\\-8=-3-5\\-8=-8\\\\plug(-5,0)\\0=-3(-5)-5\\0=15-5\\0\neq10\\\\plug\ (-2,1)\\1=-3(-2)-5\\1=6-5\\1=1\\\\plug\ (-1,-2)\\-2=-3(-1)-5\\-2=3-5\\-2=-2$

we can see ordered pair $(1,8),(-2,1)and(-1,-2)$ true for function $y=-3x-5$
