I think the right one is 3.75
Answer:
y= 6x-9
Step-by-step explanation:
1. First find the gradient between the two points. Gradient =6
2. Using the formula y= mx+c substitute the gradient into the equation. You'll get something like this: y= 6x+c
3. Substitute the point (4,15) into the equation. You'll get something like this: 15= 6(4) +c.
4. Calculate the value of c. You'll get - 9 as an answer to that.
5. Substitute the value of c into the original equation. Your final answer will be y= 6x-9
So when does y1 = y2?
