determine the equation of the line shown in the graph below. enter your answer in slope-intercept form.
Answer
Explanation:
Step1: Identify slope from graph
The line rises 1 unit for every 2 units run, so slope $m=\frac{1}{2}$.
Step2: Use point to find intercept
Substitute $(x,y)=(4,1)$ and $m=\frac{1}{2}$ into $y=mx+b$: $1 = \frac{1}{2}(4) + b$ $1 = 2 + b$ Solve for $b$: $b=1-2=-1$
Step3: Write slope-intercept equation
Substitute $m=\frac{1}{2}$ and $b=-1$ into $y=mx+b$.
Answer:
$y=\frac{1}{2}x - 1$
