Answer:
The euation of the linear function is:
- y = -1
Step-by-step explanation:
As the function has the values
- at x = 5, f(5) = -1
- at x = 0, f(0) = -1
Thus, the two points are:
- (5, -1)
- (0, -1)
Finding the slope between (5, -1) and (0, -1)
We know that the slope-intercept form of the line equation is
y=mx+b
where m is the slope and b is the y-intercept
We also know that the y-intercept can be computed by setting x=0 and finding the corresponding value of y.
so at x = 0, y = -1
Thus, the y-intercept 'b' = -1
Now, substituting m = 0 and b = -1 in the slope-intercept form of the line equation
y = mx+b
y = 0x + -1
y = -1
Therefore, the euation of the linear function is:
- y = -1
