Answer: y=4
Step-by-step explanation:
In order to find y axis interception , you need to substitute the x=0 into your equation, by doing this you get 3*2^(0)+1 which is eventually equals to 4
Answer:

Step-by-step explanation:
y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.
4 =
(3) + b
-2/3 times 3 is -2 so you can fill that in place.
4 = -2 + b
<u>+2 +2 </u>
6 = b
So the y-intercept is 6 now we can complete the equation.

Hope that helps and have a great day!
