Answer:
1.) 1/2
2.) -1
3.) 0
Step-by-step explanation:
1.) y = 1/2x
the equation is already in the slope, y-intercept form; y=mx+b were m is the slope. therefore,
m = 1/2
2.) Based on the graph the 2 points of the lines are (0,3) (2,1)
using formula [tex]m = \frac{y_{1} - y_{2} }{x_{1} - x_{2} }[/tex]
[tex]m = \frac{3-1 }{0-2}[/tex]
m = -1
3.) (-1, 2) , (3, 2)
using formula [tex]m = \frac{y_{1} - y_{2} }{x_{1} - x_{2} }[/tex]
[tex]m = \frac{2-2 }{-1-3}[/tex]
m = 0
