Slope=0; through (4,-2)

@hartnn
OpenStudy (anonymous):
this one should be easier without the fraction
OpenStudy (anonymous):
y+2=0(x-4)
OpenStudy (anonymous):
then -2 on each side?

hartnn (hartnn):
yes
but what is 0*(anything) = ... ?
OpenStudy (anonymous):
0
hartnn (hartnn):
correct
so u have
y+2=0
thats it!
its already in standard form
OpenStudy (anonymous):
oh wow lol. i need to remember that the parentheses are multiplication..
OpenStudy (anonymous):
should i make a new problem for the next one? or do it here

your wish :)
OpenStudy (anonymous):
next one is Slope = -1; through (-3,5)
OpenStudy (anonymous):
one sec to set it up
OpenStudy (anonymous):
y-5=-1(x+ -3)
OpenStudy (anonymous):
+ - doesn't seem right

hartnn (hartnn):
y-5=-1(x- (-3))
keep brackets to avoid confusion
hartnn (hartnn):
a-(-b) = a+b
OpenStudy (anonymous):
y-5=-1(x+3)
OpenStudy (anonymous):
+5 +5?
hartnn (hartnn):
yes
or since there is no fraction here
you can also distribute -1 to (x+3) first

OpenStudy (anonymous):
y-5=-1x-3
OpenStudy (anonymous):
right
hartnn (hartnn):
yes
now add 5 on both sides
OpenStudy (anonymous):
y=-1x+2
hartnn (hartnn):
correct
1x = x
add 'x' on both sides

add x to 1x and 2? or y and 2
hartnn (hartnn):
y = -x +2
+x +x
y+x = +2
OpenStudy (anonymous):
is that all?
hartnn (hartnn):
yep
y+x =2
or
x+y =2
is in the standard form
ax+by=c
OpenStudy (anonymous):
awesome
