Question

What is the y-intercept of the function? y = (8.1)x

A. 8.1
B. 1
C. 0
D. Cannot be determined

wouldnt it be 1?

Answer 1

zero

Answer 2

The y-intercept is where the graph crosses the y-axis. The only place any graph does this is when x = 0.

Answer 3

when x = 0, y = 0. so C.

Answer 4

The y axis is the line x = 0. So you have a system in which

y = 8.1x and x = 0. Plugging in 0 for x gives y = 8.1(0) = 0. Therefore the answer is C.
