in the slope intercept formula
, we get,
Thus, the equation of the line in slope intercept form is
The Correct option is D). y=1x+1 And y=2x+2
Step-by-step explanation:
The equation of a line is given as y=mx+c.
where m=slope of line and c=y intercept
The slope of line is given as m=
Solving for Redline:
From the given graph, redline passes through (-1,0) and (0,1)
The slope of Redline is m=
The slope of Redline is m=
The slope of Redline is m=(1)
And Y-intercept is 1

Solving for Blue-line:
From the given graph, Blue-line passes through (-1,0) and (0,2)
The slope of Blue-line is m=
The slope of Blue-line is m=
The slope of Blue-line is m=(2)
And Y-intercept is 2
The equation of a Blue-line is given as y=2x+2
The Correct option is D). y=1x+1 And y=2x+2
