Question

The graph shows the cost of purchasing T-shirts. Find the constant rate of change for the graph. Then explain what points (0,0) and (1,9) represent​

Answer 1

Solution

As to the attachment graph ;

• we observed that the constant rate is 9
• each step of horizontal change correspond to 9 steps of vertical change

Now,

according to the question

it is found as the division below ;

• (9-0)/(1-0)=9/1 = 9

the point which is indicating the starting point ;

• (0,0)

the point which indicate the cost of one t-shirt ;

• (1,9)

Answer 2

Answer:

See below

Step-by-step explanation:

As per the attached graph we observe that the constant rate of change is 9 as each step of horizontal change corresponds to 9 steps of vertical change

It is found as the division below:

• (9-0)/(1-0) = 9/1 = 9

Point (0, 0) indicates the start point

Point (1, 9) indicates the cost of 1 t-shirt
