$f(10) = $ the value of $y$ in the row where $x = 10$

thank you

whpalmer4 · Answer

looks like the equation for $f(x) = \frac{5}{2}x-5$

whpalmer4 · Answer

To find that, I took two points, (2,0) and (4,5), found the slope between them by dividing the change in the y values (5-0 = 5) by the change in the x values (2 - 0 = 2), giving me a slope of 5/2.  Then I used the point-slope formula $$y-y_0 = m(x-x_0)$$to fit the line:$$y-0 = (5/2)(x-2)$$$$y = \frac{5}{2}x-5$$
