So for this, I'll be using slope-intercept form, which is y=mx+b (m = slope and b = y-intercept).
So the slope formula is . To get the most accurate results, use the first and last point, which is (1,1) and (10,94) and solve from there:
Now that we know the slope, just plug in the slope and a coordinate (I'll be using (10,94)) to solve for the y-intercept.
Now that we know both the y-intercept and the slope, we can form our equation as f(x) = -9 + 10.3x, or the third option.
