Graph using the intercept method: 2x + y = 4.

Question

i just cant get it

Answer 1

First solve for y
y = -2x + 4
which is like
y = m x + b
Now, when x = 0, y = 4 in other words (0,4)
that is the meaning of intercept, b, in y = m x + b,---- where the line hits the y axis which is where x = 0
so you make that pencil mark at (0,4)
Now the slope, m is -2
So from your point at (0,4) go right one and down m or -2 which is y=4-2 = 2
and mark that point (1, 2)
Two points determine a straight line. Draw your line through those two points for all real x and all real y

Answer 2

2x+y=4
-2x -2x
-----------
y=-2x+4

k now when u graph u go up 4 than from that point u go up and over to the left once

Answer 3

britnee

the slope , m, is -2
go left one and up 2
or right one and down 2

Answer 4

Stupid idiot
