Question

Explain how to graph x + 3y = 3 using the x- and y-intercepts method. Be sure to use complete sentences and use the x- and y-intercepts method only.

for 8 points

Answer 1

Answer 2

to find the x intercept substitute the y for 0 and find value of x
same for y intercept substitute the x for 0 and find value of y

Answer 3

??

Answer 4

when you substitute the x for 0 then you have
0 + 3y = 3
3y = 3
y = 1 so the y-int = (0,1)

now try to find the x int

Answer 5

what you can also do is substitute x = 0, to give 3y = 3, y = 1, to get the first coordinate (0,1), then substitute y = 0, so x = 3, and you have another co ordinate (3,0). then join a line from one point to the other, and continue the line from both sides

Answer 6

x+3(0)=3
x+0=3
x=3

correct ?

Answer 7

so 3,0

Answer 8

good job, so the x-int = (3,0)

now you have two points (0,1) and (3,0)
to graph join the lines

Answer 9

oh ok so that it ???

Answer 10

if yes thank you

Answer 11

yw :)

Answer 12

could you help with this as well please

Answer 13

sure, what do you need help with

Answer 14

ok, first you need to find the slope, we use formula
y2-y1
-----
x2-x1

Answer 15

you have points (0,4) and (-2,8)
do you know how to plug in formula

Answer 16

x1,y1 x2,y2
(0 , 4) (-2,8)
