Answer: For the first equation, the answer is #5. For the second equation, the answer is #10, for the third equation, the answer is #2, and for the fourth equation, the answer is #1.
Explanation:
In order to find the Y-intercept for functions, you need to plug in x=0.
For the first equation, you have
. Plug in 0 for all the x values. You get
. Solve that and you're left with -3 as your y-int. Therefore, the answer will be (0, -3) AKA #5.
Follow these steps for the rest of the problems, I'm not writing the step by steps for the rest because they are very similar.
1. plug in 0 for the x values
2. simplify equation till you have one value
3. That value you just found is the y- int.
4. substitute that value for y in this: (0,y)
Hope that helped! if you need further help, I can add another answer for the rest of the equations.
