Hi! I will help with the second pic!
Explanation:
So the first step is too know the formula: y=mx+b (m being the slope and b being the y-intercept)
Now b is what you start with. So for example is your graphing y=3x+4 you would have to go up 4. Then you have too turn the slope into a fraction. So it would be 3/1. Start by going up 4 the go up 3 right one. (This isn’t the answer just an example)
Now for the answer. As we can see the orange line graph starts by going up 2. So that is our y-intercept (our b in the formula)
Now we have too find the point closest too that. Which is (5,1) Okay. Now how much did it go up from 2? It went 3 points up.
So that is our numerator. Now how much did it go to the right? 1 point to the right! So now we have our answer for the orange line one.
Answer:
Y=3x+2
