Question

Choose the correct x-intercept and y-intercept of the equation x + 2y = 4.

x-intercept: (0, 2), y-intercept: (4, 0)

x-intercept: (2, 0), y-intercept: (4, 0)

x-intercept: (0, 4), y-intercept: (2, 0)

x-intercept: (4, 0), y-intercept: (0, 2)

Answer 1

substitute the x for 0 to find the y-int
substitute the y for 0 to find the x-int

Answer 2

for example, to find x-int, substitute the y for 0, so you have
x +2y = 4
x + 2(0) = 4 so what is x ???

Answer 3

um...4?

Answer 4

or zero?

Answer 5

right, the x-int = 4, so it is (4,0)
now try to find the y-int

Answer 6

0,-2 ?

Answer 7

why negative??

Answer 8

i dont know i thought maybe

Answer 9

ok, you have

x + 2y = 4 when x = 0 then
0 + 2y = 4

Answer 10

so you have

2y = 4
-- --
2 2

Answer 11

y=4

Answer 12

y=2

Answer 13

2

Answer 14

ok, now you have it right, so you have
x-int = (4,0) and y-int = (0,2)

Answer 15

so would the answer be

Answer 16

x-intercept: (4, 0), y-intercept: (0, 2)

Answer 17
