Question

Make the graph of
`y = 3x - 1`

Answer 1

Step-by-step explanation

Step 1

`y=3x-1`

this is the equation of a line in the form

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

to graph the line, we need at least 2 points,

let

P1, when x=0

`\begin{gathered} y=3x-1 \\ y=3\cdot0-1 \\ y=0-1 \\ y=-1 \\ \text{hence} \\ P1(0,-1) \end{gathered}`

now, P2

when x= 2

`\begin{gathered} y=3x-1 \\ y=3\cdot2-1 \\ y=6-1 \\ y=5 \\ \text{hence} \\ P2(2,5) \end{gathered}`

Step 2

graph the line:

draw a line that passes trougth the points P1 and P2
