Answer:
equation of the line is y=x+1
Step-by-step explanation:
the equation of a line has the form y = mx + b
while m is for the slope and b is for the y-intercept.
you can see from the graph that the line intercepts the y-axis at y=1 this is the b.
you can get the slope of the graph by taking two points from the graph lets say (1, 2) and (3, 4) then using this formula:
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
in our case it will be:
[tex]m=\frac{4-2}{3-1} = \frac{2}{2}=1[/tex]
then just substitute the values for m and b.
