Write the equation of the line given by the following graph in slope-intercept form.

y = x + 1

y = x – 1

y = x + 6

y = x – 6

It has an x-intercept of 6

anonymous · Answer

so it is D?

luigi0210 · Answer

x-intercept: When y=0
6=x
0=x-6
y=x-6

anonymous · Answer

thank you!! can you answer another for me?

anonymous · Answer

Write the equation of the line that passes through (–1, 4) with a slope of –1 in standard form.

 –x + 4y = –1

 x – 4y = –1

 x + y = 3

 x – y = –3

jdoe0001 · Answer

they use a different slope and x,y values, but the same thing pretty much, just solving by using the point-slope form

jdoe0001 · Answer

as you can see, just grab your values and plug them in, and solve for "y"

anonymous · Answer

ok...

luigi0210 · Answer

Use the point slope formula:
y-y1=m(x-x1)
m=slope

anonymous · Answer

ok...

luigi0210 · Answer

(-1, 4)
y1=4
x1=-1
Plug them in with the slope and solve:
y-4=-1(x+1)

alright..

luigi0210 · Answer

Did I lose you? :/

anonymous · Answer

No i just really need an answer i'm not very good at this @Luigi0210

luigi0210 · Answer

Of course you are :) 
You just need practice. 
Okay so let's solve it:
