Question

Help with this

Answer 1

The equation of the line is,

y = mx + b

m = slope
b = y-intercept

Answer 2

plugging in all the variables given to you in the question will allow you to solve for y

Answer 3

Also the following notation is used to describe a point:

(x, y)

which is seen in this question.

so, for the point (0, -2)

you know

x = 0
y = -2

Thus for your equation b = -2

this is because the definition of an intercept is when one variable in the equation is 0

For example:
so an x-intercept (not for the equation given) would look like this,

(x, 0)

Answer 4

okay well I got the y=0.5x

Answer 5

So far

Answer 6

you are correct in that m = 0.5 but you in this question b does not equal 0

Answer 7

So, to continue I would use the y-intercept

Answer 8

?*

Answer 9

Your equation needs to look like this:


y = mx + b

Answer 10

For a y-intercept you will have the point:

(0, b)

as I explained above

Answer 11

So would it be y=0.5x-2

Answer 12

correct

Answer 13

now you have the equation of the line they are talking about, all you have to do is plug in the given x and you can solve for y

Answer 14

0?

Answer 15

yup

Answer 16

So the final answer is just zero or do I have to put it as an ordered pair

Answer 17

I would imagine just the number

Answer 18

it doesnt seem to be asking for point notation

Answer 19

OKay thanks I really do appreciate help like yours :) Who guide students :))))

Answer 20

no problem also note that you just solved for the x-intercept of this equation, as the point is:

(4,0)

Answer 21

Yes I understand completely :)
