Question

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

Answer 1

I'm not very great with algebra.. Can I have some help? or maybe the answer.. either one

Answer 2

(-1, 4)
x1 y1

slope = m = -1

Answer 3

do u knw thepoint-slope form of line ? :) @beccaboo333

Answer 4

nope

Answer 5

np :)

here is the point slope form of line :-

y - y1 = m(x - x1)

Answer 6

just plugin the numbers, wat do u get ?

Answer 7

i still have no idea... i do online classes and usually just wing it at problems.. the pages to learn how to do these problems dont really explain anything well.. so everything is just confusing for me

Answer 8

i get u, lets try to figure it out quick, its easy actually

Answer 9

point slope form :-

y - y1 = m(x - x1)

Answer 10

(-1, 4)
x1 y1

slope = m = -1

Answer 11

plug above given data in point slope form :-

y-4 = -1(x- -1)

y - 4 = -1(x+1)

Answer 12

can u take it from here ? :)

Answer 13

i can try

Answer 14

good :) give it a try, if u go wrong, il correct anyways

Answer 15

just u need to put it in standard form

Answer 16

yeah if i actually was taught this while i was still in public school.. which i never was. so still kinda confusing

Answer 17

ha it can be confusing when we start,
but as u do few problems, im sure u wil feel these are simple

Answer 18

hopefully

Answer 19

y - 4 = -1(x+1)

y - 4 = -x - 1

add x both sides

y - 4 = -x - 1
+x +x


x + y - 4 = -1

Answer 20

next, add 4 both sides

x + y - 4 = -1
+4 +4

x + y = 3

Answer 21

thats ur answer
see if it makes some sense

Answer 22

it's starting to sorta come back to me how to do this. Can i have some help with 6 more problems? and thank you for the help you've already done :)
