X

Answer 1

Answer is in the graph and how to below.

given y= x + 1

Using slope intercept form y = mx + b

m = slope
b = y intercept

y = x + 1 is the same as y = 1x + 1

m = 1
b = 1

On your graph start with your y intercept, it is the point on the line ( 0, 1) where your line will cross the y axis. Place your point.
From this point, using slope of 1 which when written in y/x is 1/1. Go up + 1 and right +1 and place your point at (1, 2) do this again go up +1 and right +1 and place your point ( 2, 3) now draw your line. See attached graph.
