Question

what is the point-slope form of an equation for the line that passes through (0, -5 )with a slope of 2 a.y=2x-5b. y+5=2xc.y-5=x-2d.y=2(x+5)

Answer 1

The point slope form is:

`y-y_0=m(x-x_0)`

where m is the slope and (x0,y0) is a point of the line.

In this case, we know the point (0,-5) and the slope is m=2.

Then, we can write the equation in slope point form as:

`\begin{gathered} y-(-5)=2(x-0) \\ y+5=2x \end{gathered}`

Answer: y+5=2x (option b)
