Question

Find the slope of the line that contains the points:(-4,3) and (4,9)A. 4/3B. -4/3C.-3/4D.3/4

Answer 1

We can find the slope of a line (m) with two points (x1,y1) and (x2,y2) by means of this formula:

`m=(y2-y1)/(x2-x1)`

In this case, we have the points (-4,3) and (4,3), lets replace them into the formula above and find the value of m, like this:

`\begin{gathered} m=(y2-y1)/(x2-x1) \\ m=(9-3)/(4-(-4))=(6)/(4+4)=(6)/(8)=(3)/(4) \end{gathered}`

Then the slope of this line is 3/4
