Question

Question 1Which equation represents the line that passes through the point (4,-2)AP) with a slope of1/2

Answer 1

The point-slop form of the line equation is

`y-b=m(x-a)`

In this case m=1/2, a=4 and b=-2.

`\begin{gathered} y-(-2)=(1)/(2)(x-4) \\ y+2=(1)/(2)x-2 \\ y=(1)/(2)x-4 \end{gathered}`

You can also writ the equation in the next form

`x-2y-4=0`
