Answer 1

oh sorry i have some options i should of put down

Answer 2

(-1,5)
(1,5)
(0,-5)
(0,5)

Answer 3

another way is to not convert it to slope-intercept form. you can just susbtitute zero for x when solving for y and zero for y when solving for x

Answer 4

ok..thanks

Answer 5

5x - 2y = 10
using substitution method choice number 1 (-1, 5)
5 (-1) - 2 (5) = 10
-5 - 10 = 10
-15 = 10 is false so this is not the correct point

second choice (1, 5)
5x - 2y = 10
5 (1) - 2 (5) = 10
5 - 10 = 10
-5 = 10 is false

do you see how I am using the subsitution method, and can you do it?

Answer 6

ya so its the 4th one thats what my dad said

Answer 7

the 4th one is not correct

Answer 8

5x - 2y = 10 with point (0 ,5)
5 (0) - 2 (5) = 10
0 - 10 = 10
-10 = 10 is FALSE
