Answer:
A) -1/2
Step-by-step explanation:
The given equation is x + 2y = 3
The general form of slope-intercept form is y = mx +b, where "m" is the slope and "b" is the y-intercept.
Now let's write the given equation in slope-intercept form.
x + 2y = 3
Subtract x from both sides, we get
x - x + 2y = -x + 3
2y = -x + 3
Dividing both sides by 2, we get
2y/2 = -1/2x + 3/2
y = -1/2x + 3/2
Here the slope (m) = -1/2 and y-intercept(b) = 3/2
