Question

What is the equation in standard form of the line which passes through (-2, -3) and has a slope of 1/2

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

Answer 1

use the standard form of a straight line

y - y1 = m(x - x1)

where m = slope and (x1,y1) is a point on the line
and rearrange to get one of the above

Answer 2

You can take the points and put them in to the equation to see which one would be right. hint include the negtive sign too

Answer 3

I will give you an example and work one out.
2x + y = 4
2(-2)+(-3)=4
-4+(-3)=4
-7=4
so this one is wrong do this for all of them.
