Question

a graph of a linear equation passes through (-2,0) and (0,-6)1. Use 2 points to sketch the graph of the equation2. is 3x-y=-6 an equation for this graph? (Yes or no question)3. Explain your reason of how you know

Answer 1

1) So we can graph the point and join the points with a line so:

2) we can rewrite the equation in the form slope intercept so:

$\begin{gathered} 3x-y=-6 \\ y=3x+6 \end{gathered}$

So the answer is NO

3) because the intercept with the y axis is -6 no 6 so for that reason we know that is not the function
