Use the graph to find the values of a , b and c. State the linear relationship

between the variables x and y .​

Answer 1

Step-by-step explanation:

Given: Table of values

To find:Use the graph to find the values of a , b and c. State the linear relationship between the variables x and y .

Solution:

1. Mark the points having both values of x and y,shown black in colour.
2. Draw line by joining these points.
3. To find a,mark a line as shown in figure 2.Thus, point is (-3,-1).Value of a is -3.
4. Repeat the process for (-5,b) the point is (-5,-2).Value of b is -2.
5. Repeat for (C,4),the point is (2.5,4),value of c is 2.5

All the points are shown in red,which have unknown values.

Final answer:

$a = - 3 \\ b = - 2 \\ c = 2.5$
