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:
<h2>

</h2>
in our case it will be:

then just substitute the values for m and b.

Answer:
5a²+22a+8
Step-by-step explanation:
(5a×a)+(5a×4)+(2×a)+(2×4)
=5a²+20a+2a+8
=5a²+22a+8
