Question

3) Find the equation of the line through the point (2, 5) and with slope m = 2. Also, graph this line.

Answer 1

`\begin{gathered} y=mx+b \\ \text{where} \\ m=\text{slope} \\ b=y-\text{intercept} \end{gathered}`

Therefore,

m = 2

`\begin{gathered} 5=2(2)+b \\ 5-4=b \\ b=1 \end{gathered}`
`y=2x+1`

when x = 1, y = 3

x = 2, y = 5

x = -1 , y = -1

x = -2, y = -3
