Question

Write the equation of the line given by the following graph in standard form.

graph of a line in the coordinate plane with a slope of negative two and points at (–1, 3) and (1, –1)

2x – y = –1

2x + y = –1

2x + y = 1

2x – y = 1

Answer 1

whats the difficulty u have here ?

Answer 2

Well, I think the answer is 2x+y=1 But, I'm not sure. :/

Answer 3

using slope point form with slope -2 and point(-1,3)

y-3 =-2(x+1)
y-3=-2x-2
2x+y=1

yep u are right !!!

Answer 4

Thank you :)
