Question 209062: 2y=x+4 need the slope and intersection
Answer by nerdybill(7384)   (Show Source):
You can put this solution on YOUR website! 2y=x+4 need the slope and intersection
.
To determine the "slope" and the "y-intercept", you can manipulate the given equation into the "slope-intercept" form of a straight line:
y = mx + b
where
m is the slope
b is the y-intercept at (0,b)
.
To get it in the above form, simply divide both sides of the given equation by 2:
2y=x+4
y = (1/2)x + 2
This means:
m (slope) is 1/2
and
(0,2) is the y-intercept
.
To find the x-intercept, set y=0 and solve for 'x':
2y=x+4
2(0)=x+4
0=x+4
-4 = x
therefore,
(-4,0) is the x-intercept
