find the equation of the linear function represented by the table below in slope-intercept form.
$x$: 0, 1, 2, 3, 4
$y$: -1, 5, 11, 17, 23
Step1: Identify y-intercept (b)
When $x=0$, $y=-1$, so $b=-1$.
Step2: Calculate slope (m)
Use two points, e.g., $(0,-1)$ and $(1,5)$.
$m=\frac{y_2-y_1}{x_2-x_1}=\frac{5-(-1)}{1-0}=\frac{6}{1}=6$
Step3: Write slope-intercept form
Slope-intercept form is $y=mx+b$. Substitute $m=6$ and $b=-1$.
$y=6x-1$
