Write an equation of line in slope intercept by its graph.
Answer to Problem 36PPS
Therefore, the equation of line is
Explanation of Solution
Given information:
Graph of linear equation:
Solution:
In order to find equation of line, we need to get two points.
From the graph, we can see that line crosses at y-axis at -4 units downward from the origin. Therefore, the y-intercept is -4.
Now, if we go 2 units upward and 8 units right, we get another coordinate (8,-2).
So the slope will be,
Therefore, slope of line is
Now, put the value of slope m=
Slope- intercepts form:
Therefore the equation is
