Question

A line has a slope of zero and passes through the point (-2, 3). Which of the following points must also lie on the line?

Answer 1

Where are the following points?

Answer 2

if it has a slope of zero, then it is a horizontal line. One point on the line would be (anything for x, and 3 for y).

Answer 3

a horizontal line is represented by y = a number....that number is 3...it will always be 3. Your x can be any number, buy your y value, on this particular problem, is always going to be 3

Answer 4

that's all they give me and I have 3 possible answers

Answer 5

1- (-2, 5)
2- 5, 3)
3- (2, -3)

Answer 6

okay...look at your answer choices.
your points are set up like (x,y).
Now which one has a y value of 3 ?

Answer 7

hold on

Answer 8

answer 2

Answer 9

BINGO...you got it natasha...answer 2....good job :)

Answer 10

thank you
can you help with one more please

Answer 11

Here is something that might help you...

HOY -- stands for : Horizontal line, 0 slope, y = a number

VUX -- stands for : Vertical line, undefined slope, x = a number

oh...I can try to help

Answer 12

this one its true or false question
The set of points C(1, -1), D(3, 4), E(5, 8) are collinear.

Answer 13

well....colinear means they are on the same line...

lets make a table..
x 1 3 5
----: --- : --- : ----
y -1 4 8

so when x is 1, y = -1....when x is 3, y = 4...so far, the difference in the x's is 2 and the difference in the y's is 5....so for it to be on the same line, the difference have to be the same.
3 + 2 = 5 (correct)
4 + 5 = 9 (incorrect)...for it to be on the same line, it would have to have been 5/9

FALSE

Answer 14

thank you so much that was a lot of help

Answer 15

sorry it took so long

Answer 16

that's ok
