Question

Function lis defined by the equation r

R=5/8t - 9

Function 2 is defined by the following table,
I
Which function has a greater y-intercept?

Answer 1

Both have the same y-intercept (-9)

Explanation:

✔️Function 1, r = ⅝t - 9, is given in the slope-intercept form, y = mx + b.

b = y-intercept = -9

y-intercept for Function 1 = -9

✔️Function 2, using the table given, the y-intercept is the value of r when t = 0.

Thus, r = -9 when t = 0.

y-intercept for Function 2 = -9

✔️Both functions has the same y-intercept. None is greater than the other.
