Answers:
x intercept = 88/7
y intercept = 11
===============================================
Step-by-step explanation:
To find the y intercept, we replace f(x) with 0 and solve for x.
f(x) = (-7/8)x + 11
0 = (-7/8)x + 11
(7/8)x = 11
7x = 8*11
7x = 88
x = 88/7 is the x intercept
It is located at (x,y) = (88/7, 0)
The x intercept always occurs when y = 0.
88/7 = 12.5714 approximately, but I would stick to the fraction form since it's most exact.
-------------------------------
The y intercept always occurs when x = 0.
f(x) = (-7/8)x + 11
f(0) = (-7/8)*0 + 11
f(0) = 0 + 11
f(0) = 11 is the y intercept
It is located at (0,11)
The y intercept is much easier to find since we just need to read off the last value of the function (aka the constant value).
