Question

y=4/3x+4 find slope and y-intercept

Answer 1

The equation is in the form y = mx+b where m is the slope and (0,b) is the y-intercept.


In this case, m = 4/3 and b = 4


So the slope is 4/3 and the y-intercept is (0,4)

Answer 2

okay ty!!!!Again ;) if I wanted to graph this what might another y-intercept be?

Answer 3

that funcion is linear. there should be only 1

Answer 4

could it be none?/

Answer 5

All lines only have ONE y-intercept. This is ALWAYS the case with any line. In fact, all functions only have one y-intercept.


If you wanted another point on the other hand, plug in any x value to find its corresponding y value

Answer 6

oh ty :)

Answer 7

So for instance, if x = 3, then


y = 4/3x + 4


y = (4/3)(3)+4


y = 12/3 + 4


y = 4+4


y = 8


So when x = 3, y = 8


So we have another point (3,8)

Answer 8

So you now have two points (0,4) and (3,8)

Answer 9

got it, thanks for the example :)
