Question

find a point slope equation for a line containing the given point and having the given slope y-y1 = m (x-x1 )7. (7, 0), m = 48. (0,9), m = -2

Answer 1

We have the following:

7. (7.0), m = 4

replacing:

`\begin{gathered} y-0=4\cdot(x-7) \\ y=4x-28 \end{gathered}`

8. (0,9), m = -2

`\begin{gathered} y-9=-2\cdot(x-0) \\ y=-2x+9 \end{gathered}`
