Question

What is the y-intercept of the function y = 8x?

Answer 1

are you aware the y-intercept is the point at which the graph of the function given crosses the y-axis???

Answer 2

0

Answer 3

so if that is known, and you also know that on the y-axis, the value of your x-coordinate is zero, then what would your y-coordinate be??

Answer 4

y=mx+b. b is the y intercept y=8x is equal to y=8x+0. the y intercept is 0

Answer 5

Now what if I changed the equation to y=(8.1)x?

Answer 6

still the y intercept is 0 because 8.1 would be the slope not the y intercept

Answer 7

What about this one? y=2.1(0.15)x?

Answer 8

2.1x.15 would still be the slope and the y intercept would still be 0
