Question

Write in standard form an equation of the line passing through the given point with the given slope.

slope = –7; (–2, –2)

a.
–7x + y = –16
b.
7x + y = 16
c.
7x – y = –16
d.
7x + y = –16

Answer 1

Do you know the slope formula?

Answer 2

y = Mx = b

Answer 3

Y = Mx + b

Answer 4

It's y=mx+b

Answer 5

Now that you know the formula, where do you put the -7?

Answer 6

im not sure?

Answer 7

Standard form is Ax + By = C

Answer 8

Do you have a math textbook with you?

Answer 9

Not on me. i lent it to my friend

Answer 11

Im still confused?

Answer 12

One second. Let me explain

Answer 13

you have my attention

Answer 14

y = mx + b is an equation.
The question gives you the slope, and a pair of coordinates (-2,-2) and a slope of -7.
The first -2 in the coordinate stands for x. The second -2 in the coordinate stands for y. M is the slope, and -7 stands for the M. Plug those numbers into the equation..

Answer 15

and you get..

-2 = -7(-2) + b

Answer 16

Solve that for me

Answer 17

-2 = 14 +b

from there im stuck again?

Answer 18

Right. You need to subtract the 14 on both sides

Answer 19

-16 = B

Answer 20

Right! Now plug it into y=mx+b

y=-7x-16

Answer 21

Rearrange that into standard form.

Answer 22

A is the only reasonable answer.

-7x + y = -16

Answer 23

-7x + y = -16

Answer 24

Correct.

Answer 25

Do you understand it now?

Answer 26

Yeah. i got lost on solving for the slope intercept form. but i get it now

Answer 27

You going to close the question?
