Answer:

• Slope, m =-1

,

• Equation: y=-x+8

Explanation:

Gien the points: (x1,y1)=(3,5) and (x2,y2)=(-1,9)

Slope

[tex]Slope,m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the points:

[tex]\begin{gathered} m=\frac{9-5}{-1-3} \\ =\frac{4}{-4} \\ m=-1 \end{gathered}[/tex]

The slope of the line is -1.

Equation of the Line

We use the point-slope form to find the equation of the line.

Using point (3,5) and slope, m=-1

[tex]\begin{gathered} y-y_1=m(x-x_1) \\ y-5=-1(x-3) \\ y-5=-x+3 \\ y=-x+3+5 \\ y=-x+8 \end{gathered}[/tex]

The equation of the line is y=-x+8.
