Question

Write the equation of the line that passes through (4,1) and has a slope of -1/2.

Answer 1

`\begin{gathered} y=mx+\text{b } \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}`
`\begin{gathered} 1=-(1)/(2)(4)+b \\ 1=-2+b \\ b=1+2 \\ b=3 \end{gathered}`
`y=-(1)/(2)x+3`
