Answer to Problem 1STP
Explanation of Solution
Given information: We have given a linear graph.
Solution: From the graph, we can see that the line crosses at the y -axis at (0, 4)
So, the y -intercept (b) is = 4.
If we go 2 units downward and 3 unit right then we get another point (3, 2) on the graph
Therefore, slope =
So, the slope ( m ) of line is
Now, plug the value of slope ( m )=
Therefore, the equation of linear equation is
