Graph y =- 1/2x -5 Would the coordinates to graph be:
(0, -5) and (-2, -4)?
Remember that
If an ordered pair lies to the given line, then the ordered pair must satisfy the linear equation
so
Verify
For (0,-5)
x=0, y=-5
substitute
y=-(1/2)(0)-5 -------> y=-5 is ok
that means -----> the ordered pair (0,-5) lie to the given line
For (-2,-4)
x=-2, y=-4
substitute
y=-(1/2)(-2)-5 ------> y=-4 is ok
the ordered pair (-2,-4) lie to the given line
