Question

a.)$$x = t$$
$$y =\ −4x\ +\ 1$$ substituting$$x\ −\ y =\ −4(t)\ +\ 1$$
$$y =\ −4t\ +\ 1$$ Hence parametric equations are: $$y =\ −4t\ +\ 1\ and\ x = t$$ b.)$$x =\ \frac{t}{2}$$
$$y =\ −4x\ +\ 1$$ substituting x: $$y =\ −4(\frac{t}{2})\ +\ 1y =\ −2t\ +\ 1$$ hence the parametric equations are: $$y =\ −2t\ +\ 1x =\ \frac{t}{2}$$ Step 2 c.)$$x =\ −4t$$
$$y =\ −4x\ +\ 1$$ substituting x: $$y =\ −4(−4t)\ +\ 1y = 16t\ +\ 1$$ Hence parametric equation are: $$y = 16t\ +\ 1x =\ −4t$$
