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)

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

You need to substitute the given values into the equation y = mx + b and rearrange into standard form.
kropot72
  • kropot72
This will let you find the value of b which is the y-intercept.

okay so 5x-2y=2/3?
anonymous
  • anonymous
wait i think im off
anonymous
  • anonymous
what am i doing wrong?
kropot72
  • kropot72
Substitute the given values into y = mx + b. Then solve to find the value of b. Can you do that as a first step?
anonymous
  • anonymous
no i dont think so
anonymous
  • anonymous
this is what it looks like _x__y__
kropot72
  • kropot72
y = -2, x = 5 and m = 2/5 Plug these values into y = mx + b What do you get?
anonymous
  • anonymous
do i x 2/5 and 5?
kropot72
  • kropot72
Correct.
anonymous
  • anonymous
that would be 2
kropot72
  • kropot72
So we should have -2 = 2 + b which needs to be solved to find the value of b.
anonymous
  • anonymous
yes
anonymous
  • anonymous
ugh i dont know do we x 5 and 2?
kropot72
  • kropot72
What do you get for the value of b?
anonymous
  • anonymous
10? *I say very unsure*
kropot72
  • kropot72
Can you solve -2 = 2 + b to find the value of b?
anonymous
  • anonymous
oh wait i felt like it was harder then it was i hope would b be -4?
anonymous
  • anonymous
so it would be -2=2+-4?
kropot72
  • kropot72
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
anonymous
  • anonymous
how would i do that?
anonymous
  • anonymous
oh wait
anonymous
  • anonymous
whats a?
kropot72
  • kropot72
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.
anonymous
  • anonymous
oh okay
anonymous
  • anonymous
hahaha hold i thats so wrong
anonymous
  • anonymous
i hate math
anonymous
  • anonymous
10x-y=4?
kropot72
  • kropot72
\[\large 5(\frac{2}{5}x-y)=4\times5\] which becomes \[\large 2x-5y=20\]
anonymous
  • anonymous
oh lol i feel stupid now
anonymous
  • anonymous
thank you soooo much i think now i can figure out the rest now

  • kropot72
You're welcome :)
