Question

I need help n explainnnn please ​

Answer 1

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=$\frac{(Y2-Y1)}{(X2-X1)}$

Solving for Redline:

From the given graph, redline passes through (-1,0) and (0,1)

The slope of Redline is  m=$\frac{(Y2-Y1)}{(X2-X1)}$

The slope of Redline is  m=$\frac{(1-0)}{(0-(-1))}$

The slope of Redline is  m=(1)

And Y-intercept is 1

The equation of a Redline is given as y=1x+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=$\frac{(Y2-Y1)}{(X2-X1)}$

The slope of Blue-line is  m=$\frac{(2-0)}{(0-(-1))}$

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
