The y-intercept is -4, the slope is 1/2 and the slope is positive
The other point is (2, -3)
What is the y-intercept?
From the question, we have the following parameters that can be used in our computation:
f(x) = 1/2x - 4
A linear function is represented as
f(x) = mx + c
Where
c = y-intercept
m = slope
Using the above as a guide, we have the following:
c = -4
So, the y-intercept is -4
What is the slope?
Recall that
m = slope
So, we have
m = 1/2
This means that the slope is 1/2
Is your slope positive or negative?
The slope is 1/2
This is so because 1/2 is greater than 0
Explain how you plotted your second point
Set x = 2
So, we have
f(2) = 1/2 * 2 - 4
f(2) = -3
So, the other point is (2, -3)
