Step-by-step explanation:
We need to find equation from the table given
x f(x)
3 -5
7 -2
11 1
15 4
We can write equation in the form of
where m is slope and b is y-intercept.
Finding Slope
We can used the slope formula to find slope:
From the table we have:
Putting values and finding slope
So, we get slope
Now, finding y-intercept
Using the slope and point (3,-5) we can find y-intercept
The y-intercept is
So, the equation having slope and y-intercept
will be:
The required equation is:
