Question

I NEED SOME EMERGENCY HELP WILL MEDAL AND FAN PLEASE!!!!

Indicate in standard form the equation of the line passing through the given point and having the given slope.

D(5, -2) m =

#2ndicate in standard form the equation of the line passing through the given points.

B(0, 0), C(4, -4)

#3ndicate in standard form the equation of the line passing through the given points.

P(6, 2), Q(8, -4)

#4Indicate in standard form the equation of the line passing through the given points.

G(4, 6), H(1, 5)

Answer 1

What is the value of m for the first part? You appear to have missed typing it.

Answer 2

2/5

Answer 3

sorry

Answer 4

You need to substitute the given values into the equation
y = mx + b
and rearrange into standard form.

Answer 5

This will let you find the value of b which is the y-intercept.

Answer 6

okay so 5x-2y=2/3?

Answer 7

wait i think im off

Answer 8

what am i doing wrong?

Answer 9

Substitute the given values into y = mx + b. Then solve to find the value of b. Can you do that as a first step?

Answer 10

no i dont think so

Answer 11

this is what it looks like
_x__y__

Answer 12

y = -2, x = 5 and m = 2/5
Plug these values into
y = mx + b
What do you get?

Answer 13

do i x 2/5 and 5?

Answer 14

Correct.

Answer 15

that would be 2

Answer 16

So we should have
-2 = 2 + b
which needs to be solved to find the value of b.

Answer 17

yes

Answer 18

ugh i dont know do we x 5 and 2?

Answer 19

What do you get for the value of b?

Answer 20

10? *I say very unsure*

Answer 21

Can you solve
-2 = 2 + b
to find the value of b?

Answer 22

oh wait i felt like it was harder then it was i hope would b be -4?

Answer 23

so it would be -2=2+-4?

Answer 24

Yes, b = -4.
So we now have
\[\large y=\frac{2}{5}x-4\]
which needs to be rearranged into standard form
ax + by = c

Answer 25

how would i do that?

Answer 26

oh wait

Answer 27

whats a?

Answer 28

First interchange the left and right sides to give
\[\large \frac{2}{5}x-4=y\]
Then rearrange to give
\[\large \frac{2}{5}x-y=4\]
Now you need to remove the fraction by multiplying both sides by 5.

Answer 29

oh okay

Answer 30

hahaha hold i thats so wrong

Answer 31

i hate math

Answer 32

10x-y=4?

Answer 33

\[\large 5(\frac{2}{5}x-y)=4\times5\]
which becomes
\[\large 2x-5y=20\]

Answer 34

oh lol i feel stupid now

Answer 35

thank you soooo much i think now i can figure out the rest now

Answer 36

You're welcome :)
