On the Cartesian plane below, graph the equation `y-1=-1/2x`.
Clearly label the coordinates of the intercepts with both the `x` and `y`-axes. (2 marks)
--- 0 WORK AREA LINES (style=lined) ---
`y-1=-1/2x\ \ =>\ \ y=-1/2x+1`
`ytext{-intercept = 1, gradient}\ = -1/2`
`xtext{-intercept occurs when}\ y=0:`
`0=-1/2x+1\ \ =>\ \ x=2`
On the Cartesian plane below, graph the equation `y=3x+2`.
Clearly label the coordinates of the intercepts with both the `x` and `y`-axes. (2 marks)
--- 0 WORK AREA LINES (style=lined) ---
`ytext{-intercept = 2, gradient = 3}`
`xtext{-intercept occurs when}\ y=0:`
`0=3x+2\ \ =>\ \ x=-2/3`
On the Cartesian plane below, graph the equation `y=2x-1`.
Clearly label the coordinates of all intercepts. (2 marks)
--- 0 WORK AREA LINES (style=lined) ---
`ytext{-intercept = –1, gradient = 2}`
`xtext{-intercept occurs when}\ y=0:`
`0=2x-1\ \ =>\ \ x=1/2`
Which of the following could be the graph of `y= -2 x+2`?
