Question

I dont know what to do.
It says to find the slope of the lind that crosses these points.
And it gives me some slopes like: (3,5) and (1,9)

Answer 1

Slope=$\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$

(3,5) and (1,9)
x1=3
y1=5
x2=1
y2=9

Slope=$\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$
Slope=$\frac{ 9- 5 }{ 1 - 3}$
Slope=$\frac{4}{ -2}$
Slope=$-\frac{4}{2} or -2$

Answer:Slope=-2
