Answer:

y-9=1(x-3)

Step-by-step explanation:

The point-slope form of the equation of a line is given as:


y-y_1=m(x-x_1)

Given the points (-1,5) and (3,9).

Step 1: We find the slope.


\begin{gathered} \text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =(9-5)/(3-(-1)) \\ =(4)/(3+1) \\ =(4)/(4) \\ m=1 \end{gathered}

Step 2: Using the point (3,9), x1=3, y1=9

Therefore, the equation in point-slope form is:


y-9=1(x-3)
