Answer 3

This is a horizontal line, so the slope is 0.

Answer 4

to work out the equation of a line, we will start by finding the gradient of the line also known as the slope


\[m=\frac{ y _{2}-y _{1} }{ x _{2}-x _{1} }\]
where \[(4,7)=(x _{1},y _{1})\]
and
\[(0,7)=(x _{2},y _{2})\]

now the standard equation of a line
\[y-y _{1}=m(x-x _{1})\]

Answer 5

0? Alright, thank you. How would I write it in standard form though? That's what I cannot figure out.

Answer 6

Plug in what you know:
y-7=0(x-4)

Answer 7

I suck at standard form

Answer 8

Simplify, and get it into standard form.

Answer 9

standard form is y=mx+c
where m is the slope and c is the intercept

Answer 10

That's not standard form. y=mx+b is slope-intercept form.

Answer 11

lol i remember now, you are the person who doesn't want me to help you sorry

Answer 12

Lol it's not that. I've been b*tchy these past few days to everybody. I'm sorry for that

Answer 13

oh it is fine lol, but both are the slope intercept form, it just depends what book or teacher you get, some use y=mx+a
good luck with your other questions

Answer 14

I do online school so I have to teach myself -_- Lol I wish they gave me books. I just have the Internet

Answer 15

I don't understand how to get it into that form though. I have it all wrote down, like all my work. It's just not clicking in my head lol

Answer 16

yeah self teaching is hard

anyways to finish off your question
use
\[y-y _{1}=m(x-x _{1})\]

substitute your values in
where
(4,7)=(x1,y1)

so you get
y-7=0(x-4)

y-7=0
y=7

Answer 17

Write it in slope-intercept form, and then change it to standard form=
y=0x+7----->y+0x=7

Answer 18

The standard form and answer is y+0x=7

Answer 19

THAT'S WHAT I HAD! It just didn't look right to me lol

Answer 20

I wish I could give you both a medal!

Answer 21

give credit to him

Answer 22

he deserved it
