A circle is centered at C(−1,−3) and has a radius of 6.Where does the point P(-6,-6) lie? A. Inside the circle B. on the circle C. outside the circle
@563blackghost
A. correct ?
Yup
Given points A(-2, -4), and B (4, 8), which of the following represents the midpoint of segment AB? A. (-3, -2) B. (2, 4) C. (-6, -4) D. (1, 2)
What answer do you think et is?
i think D if i'm not mistaken
Correct cx
it is ?
yes
Given points A(1, 3) and B (3, 7), which of the following represents the distance of AB¯? A.√20 B. √116 C. √14 D. √6
how bout dis one? what do you think the answer is?
c.
Mmm not quite. Use distance formula. \(\large\bf{d=\sqrt{(7-3)^{2}+(3-1)^{2}}}\)
d = 2√5
well yes, but the answers are simplified down to radical form, so it would be just \(\sqrt{20}\).
are not*
oh ok
A.
yes
The equation of the line that has a slope of -1 and goes through (-3,0) is: A. y = -x B. y = -x - 3 C. y = x - 3 D. y = -x + 3
what answer do you think this one is?
B
correct
A. In step 1, she compares the distances between the wrong pairs of points. B. In step 2, she incorrectly calculates the distance between (3, 1) and(3, –4) . C. In step 5, she simplifies incorrectly. D. In step 4, she makes a sign error.
i think the answer is D
I would agree.
that was incorrect
welp, which was the answer?
It didn't say
oh i see it was A
I didnt read it correctly, instead of comparing the points that she is trying to prove with the center, she compared it with the other point on the graph. Sorry.
oh well What is the equation of the line that is perpendicular to this line and passes through (-6, -2)? https://learning.k12.com/content/enforced/437405-COF_ID125380/G-GPE.B.5%20Q2.JPG?_&d2lSessionVal=gIqbusDzQX5eWYCxepgrlqzgn A. y = −2/3x − 6 B. y = −2/3x − 2 C. y = 3/2x +7 D. y = 3/2x − 4
Which do you think is the answer to dis one?
D
or C
Mmm which are you more confident in?
D
Not quiet. The slope is correct but the y-intercept is not. You need to plug in your point in \(\bf{y=\frac{3}{2}x+b}\) to find `b`. \(\large\bf{-2=\frac{3}{2}(-6)+b}\) What does b equal?
b = 7
Correct, so it is C.
kk let me start a new question
