explanation
Answer: y=6x+7
Step-by-step explanation:
To find the equation of the line, we want to find the slope with the formula
.

Now that we know th eslope, we can start to fill out the equation. To find the y-intercept, we can plug in a given point and solve.
y=6x+b
1=6(-1)+b [multiply]
1=-6+b [add both sides by 6]
b=7
Now, we know the equation is y=6x+7.
Answer: What exactly do you need help with
F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.
