Answer 1

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:

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

in our case it will be:

$m=\frac{4-2}{3-1} = \frac{2}{2}=1$

then just substitute the values for m and b.
