Answer:
slope is -2
Step-by-step explanation:
Step one:
given data
the coordinate is (1, 9) and (4, 3)
x1=1
y1=9
x2=4
y2=3
the expression for the slope of a line is given as
[tex]slope=\frac{y2-y1}{x2-x1}[/tex]
substitute our data into the expression we have
[tex]slope=\frac{3-9}{`4-11}\\\\slope= \frac{-6}{3} \\\\slope=-2[/tex]
The slope of the line is -2
