Question

I have some math questions that I'm having a little trouble figuring out. If someone could please help me, I will medal and all help is
appreciated!

I have to write an equation for each condition listed.

1. The line with a slope of 7 and a y-intercept of -1 (in slope-intercept form)
2. The line that passes through (1, -5) and has a slope of 3 ( in point-slope form)
3. The vertical line that passes through (-7, 4)
4. The horizontal line that passes through (-7, 4)

Thanks again!

Answer 1

As a start, would you please type in the "slope-intercept form" of the equation of a straight line?

Answer 2

I'm sorry, but what do you mean?

Answer 3

Have yo seen this before?

y = mx + b

Answer 4

I think so

Answer 5

Its the slope intercept form of a straight line

do you know what m and b are?

Answer 6

Oh okay and no I don't
I really don't understand math :/

Answer 7

This is what is caalled a 'general form'.

m is the slope of the line and b is the y-intercept
y = b when x = 0:-

y = m(0) + b = 0 + b = b

Answer 8

Okay

Answer 9

examples of this type are
y = 2x + 3
y = 0.5x - 3

Answer 10

If you look at your number one you can find the equation by replacing m by the given slope and b by the given y-intercept.

Answer 11

Ok...

Answer 12

m = 7 and b = -1

so y = ?

Answer 13

@Speedy2197 YOU LOOK LIKE ARIEL! FROM THE MOVIE THE LITTLE MERMAID

Answer 14

Y would =
I'm not sure...
Like I understand what you're saying, but I'm just not sure what it would =

Answer 15

@123AB456C Thanks lol
My real name is actually Ayriel
Ariel, but with a y

Answer 16

y = mx + b

just replace m by 7 and b by -1

Answer 17

Okay and what does the x represent in the mx?

Answer 18

the x and y are variable
y depends on the value of x and vice versa
just worry about the costants in the equations - m and b

Answer 19

Okay

Answer 20

all you have to do is replace m and b in the general equation by 7 and -1...
its easy

Answer 21

I understand that problem now, thank you. You explained it well

Answer 22

yw

Answer 23

How do I solve number 2,3, and 4 though?

Answer 24

first what is the answer to number 1?

Answer 25

m=7
b = -1
y=mx+b

Answer 26

but you havent replaced the m and b in the equation
