Question
the table represents the change in ( f(x) ) for given values of ( x ).
| ( x ) | ( f(x) ) |
|---|---|
| ( -1 ) | ( -5\frac{2}{5} ) |
| ( 0 ) | ( -6 ) |
| ( 1 ) | ( -6\frac{3}{5} ) |
| ( 2 ) | ( -7\frac{1}{5} ) |
a ( f(x) = x - \frac{3}{5} )
b ( f(x) = -\frac{3}{5}x - 6 )
c ( f(x) = -\frac{5}{3}x + 6 )
d ( f(x) = x - 6 )
e ( f(x) = x - \frac{2}{5} )
Step1: Find the slope (m)
Use two points, e.g., \((0, -6)\) and \((1, -6\frac{3}{5})\). The slope \(m=\frac{y_2 - y_1}{x_2 - x_1}=\frac{-6\frac{3}{5}-(-6)}{1 - 0}=\frac{-\frac{3}{5}}{1}=-\frac{3}{5}\).
Step2: Identify the y-intercept (b)
When \(x = 0\), \(f(x)=-6\), so \(b=-6\).
Step3: Write the equation
Using the slope - intercept form \(f(x)=mx + b\), substitute \(m = -\frac{3}{5}\) and \(b=-6\). So \(f(x)=-\frac{3}{5}x-6\).
