Question

On the same graph paper. plot the graph of y=x-2, y=2x+1 and y=4 form x=-4 \ to 3

• A. (i) passes through (-2,0), m=1. (ii) passes through (1,0), m=2.
  (iii) is a line segment, parallel to the X-axis, extends from x=-4 to x=3.
• B. (i) passes through (0,-2), m=1. (ii) passes through (0,1), m=2.
  (iii) is a line segment, parallel to the X-axis, extends from x=-4 to x=3.
• C. (i) passes through (0,-2), m=2. (ii) passes through (0,1), m=1.
  (iii) is a line segment, parallel to the X-axis, extends from x=-4 to x=3.
• D. (i) passes through (0,-2), m=1. (ii) passes through (0,1), m=2.
  (iii) is a line segment, parallel to the Y-axis, extends from x=-4 to x=3.

Answer 1

The correct option is B (i) passes through (0,-2), m=1. (ii) passes through (0,1), m=2.

(iii) is a line segment, parallel to the X-axis, extends from x=-4 to x=3.
As shown in figure the first line passing through $(0,-2)$ and on comapring line $y=x-2$ with $y=mx+c$ where the slope $m=1$

and comparing the second line $y=2x+1$ where $m=2$ and passing through point $(0,1)$

and AS we can see in figure the line $y=4$ is parallel to $X-axis$
