Question

find the x and y intercept of the line that passes through the given points

(-2,8),(4,2)

Answer 1

i know the slope which is -6/6 0r -1

Answer 2

then i got y-8=-1(x+2)

Answer 3

what do i do next?

Answer 4

oh thats easy use the y intercept formula y = mx + b AND JUST plug in each

Answer 5

im i correct?

Answer 6

but what will b be will it be x1 or y1

Answer 7

m=y2-y1\x2-x1
(x1,y1)=(-2,8)
(x2,y2)=(4,2)
m=2-8\4+2
m=-6\6
m=-1
by using point slope form
y=mx+b
y=-x+b
for x intercepts put y=0
0=-x+b
x=b
for y intercapt put x=0
y=b
both have same intercept points

Answer 8

oooohhhhhhh

Answer 9

Can i plz have a medal for trying :) and giving u the formula?

Answer 10

@angelkitty456

Answer 11

also will why be -x then for y or -1

Answer 12

yes -x would just be -1 and I'm not sure about y

Answer 13

the answer is x is 6 and y is 6 but how do i show my work

Answer 14

hmmm @angelkitty456

Answer 15

(3,-8),(-4,13)

Answer 16

Are you trying to find the slope?

Answer 17

no im trying to find the and y intercepts

Answer 18

the x and y intercepts

Answer 19

you can find the x and y intercepts from the slope and the points you are given

Answer 20

well for x i got 2 and for y i got 3 i think that is wrong though

Answer 21

Ok, so, we first need to find the slope of this function: use the slope formula: (y2-y1)/(x2-x1)=m\[(13-(-8))/(-4-3)= (13+8)/(-7)=21/-7=-3\]
From then, you know that the slope, m=-3.
From there, you are able to find b, the y-intercept with the formula y=mx+b; you know y, x, and m, just solve for b. The way you do this, is plug in any of the two points given, then slove:\[13=(-2)(-4)+b \rightarrow13=8+b \rightarrow 5=b\]With us knowing now the y-intercept, we are enabled to apply the slope for ANY point: y=mx+b... y=-2x+5
Since we found the y-intercept, b , which was 5, we just need to find the x-intercept; so make the function equal to 0.\[y=-2x+5\rightarrow 0=-2x+5\rightarrow-5=-2x \rightarrow(5/2)=x\]
Hope this helped, if you need more elaboration, feel free to type back :) @angelkitty456

Answer 22

i have another it is (5,0.4)

Answer 23

(5,0.4) AND (-1,-2)

Answer 24

You should practice by solving it, and checking your answer (I will check it, if you so desire).

Answer 25

i found thatand i got it but i had a new set posted above (5,0.4),(-1,-2)
please help me

Answer 26

for slope i got -2,4/6 but then what do i do
