Question

how to do you look for the y-coordinate or 'b' in the slope-intercept form equation: y=mx+b?

Answer 1

"m" is the slope of the line
"b" is the y-intercept
The equation of form "y=mx+b" is a linear equation

Answer 2

the question is "A line passes through (0,0) and (1,1). Find the slope." I dont know what to use and how to solve this thing

Answer 3

m=y2-y1/x2-x1

Answer 4

The slope is the measure of steepness of a line.
And we measure that by finding the ratio of difference in "y-coordinate" and "x-coordinate"

Answer 5

Correct, you have been given two points, use the formula you gave me to find the slope.

Answer 6

my answer is 1/1 and simplified it to 1. so m=1 is my answer correct?

Answer 7

Correct!, so what should be the equation of a line that passes through point (0, 0) and (1, 1)?

Answer 8

am i supposed to use y=mx+b? (just guessing, im sorry)

Answer 9

yes, you have to replace "something" in y=mx+b, what letter will you replace with the slope you found?

Answer 10

m :D so it'll be y=1x+b? :D

Answer 11

correct, but now what is the y-intercept which is "b"?

Answer 12

that's the problem :( i dont know how to look for the y-intercept :(

Answer 13

And when a line passes the y-axis, what is x-coordinate at the point?

Answer 14

so the y-intercept is 1? (lol i apologize for my stupidity)

Answer 15

we know when the line cuts y-axis, x-coordinate is "0" But that was a mere example. Tell me from the points you have been given, what is y-intercept?

Answer 16

1? lol

Answer 17

You are given two point (0, 0) and (1, 1) , in which point x-coordinate is "0"?

Answer 18

oh. 0 then lol

Answer 19

so it'll be y=1x+0??

Answer 20

Correct! because x-coordinate is "0" in the first point, therefore, you look for y-coordinate in that point but y-coordinate is "0" too, therefore, y-intercept is "0"

Answer 21

correct, and if you simplify you get \[y=1x+0 \rightarrow y=x\]

Answer 22

and then if you feel you made a mistake you can verify if the line passes through the points you are given, when x=0, y=0 and when x=1, y=1 therefore the equation is correct.

Answer 23

Ah! is y=1x-0 the final answer or there's more?
its not in the choices tho :(

Answer 24

Yes, it's the final answer in form y=mx+c

Answer 25

but its not in the choices :(

Answer 26

if the question is asking you to find the slope, then the answer is "1", and if the question is asking you to find the y-intercept then the answer is "0"

Answer 27

the question is "A line passes through (0,0) and (1,1). Find the slope." Therefore, the answer is "1"

Answer 28

You mentioned "y=mx+c" in your original question so I thought you need the equation of the line.

Answer 29

Sorry Late reply. THANK YOU SO MUCH!! YOU ROCK :))
