Write the equation of line in slope intercept for given graph.
Answer to Problem 33PPS
The equation of line is
Explanation of Solution
Given information:
Graph of linear equation:
Formula Used: Slope- intercepts form:
Calculation:
In order to find the equation of line, we need to get two points.
From the graph, we can see that the line crosses y-axis at 4 units upward from the origin. Therefore, the y-intercept is (0, 4).
Now, if we go 3 units down and 5 units right, we get another coordinate (5, 1).
So the slope will be,
Therefore, slope of line is
Now, plug the value of slope (m) =1 and y-intercept (b) = 4 in slope intercept form of equation
We get
Therefore, the equation of the line for the given graph is
