help please
@563blackghost
Yes?
sorry, ill get the question
@563blackghost
We would need to find the base and height of the triangle. If we plot the triangle we see that (-4,2) and (1,2) lie on the same y-value so the distance between is 5. Now we need to find the height..
One second I put down the distance between the wrong points.
\(\huge\bf{d=\sqrt{(-4-(-5)^{2}+(2-(-4)^{2}}}\) We find the distance between `(-4,2) and (-5,-4)`
so 15^2?
We would simplify it. \(\huge\bf{\sqrt{(1)^{2}+(6)^{2}}}\) Simplify. \(\huge\bf{\sqrt{1+36}}\) Add. \(\huge\bf{\sqrt{37}}\) So the height is \(\large\bf{\sqrt{37}}\). We would now multiply the height and the base and then divide that by two. \(\huge\bf{A=\frac{\sqrt{37} \times 5}{2}}\)
You would input the answer as a decimal.
Do you mean 15 as your answer?
If so, then yes that is correct :) Though I do not know if you would input it as `15.2` or `15` itself.
can you help me with some more?
Im sorry but I have to take my leave for today. Though I do believe @3mar can help :)
I will not be late for any help. 3 minutes, please! Thank you for your confidence, @563blackghost!
;)
Well, I am here.
Sorry for late @princeevee

Do you know the concept of the parallel and perpendicular lines?
im a little fuzzy with it
For all parallel lines, they have the same slope. For the perpendicular lines, their slopes' product is \[m_1×m_2=-1\]
so the second one goes into the parallel?
"so the second one goes into the parallel??" ???
THE SECOND ONE IN THE ROW GOES IN THE PARALELL AREA DOES IT?!
-2x+y=-4 Parallel...Correct!
and the fourth one?
Don't know?
the fourth one goes in the parallel?
Sorry the secon does not go in the parallel as the original function has a slope of -1/2 \[x+2y=6\] \[2y=-x+6\] \[y=-\frac{ 1 }{ 2 }x+6\] \[y=mx+b\] \[m=-\frac{ 1 }{ 2 }\]
so which ones go in which?
@3mar
Ok the slopes of the functions in the row would be as follows: 1. -1/2 2. 2 3. 1/2 4. -1/2 did the math and fund out which is the same as -1/2 and which is the negative reciprocal of -1/2.....
i would guess 2 and 3 are the negative ones
It is not correct, because when x goes to the other side, its sign changes. Got that?
ok
Satisfied?
well i still dont know which ones go in which? is 2 and 3 supose to be in the niether pile?
1 and 4 go to "parallel" 2 goes to "perpendicular" 3 goes to "neither"
@princeevee
okay thanks , can you help with some more?
Satisfied of this firstly?
yes
I am happy to hear that.
Can we start in new post, please?
Thank you for the medal!
