Question

Read the graph and answer the following questions :
1) What do you observe from this graph.
2) Write equation of all for line from top to bottom lable them as line 1, line 2, line 3 and line 4.​

Answer 1

Step-by-step explanation:

This is a graph represting straight lines which are parallel as well.

All the lines are parallel, and, hence, all of them have same slope, that is tangent of angle of incidence.

Here, slope = tan0° → slope = 0

(ii): let any point on Y-axis. Let ( 0, 4 ).

As discussed above, slope = m = 0.

Equation:

= > y - 4 = 0( x - 0 )

= > y - 4 = 0

= > y = 4

Similarly, equation of line:

1: y = 4

2: y = 2

3: y = - 1

4: y = - 3
