The slope-intercept expression for the graph is y = -x + 5
The equation of the line can be expressed in the form ;
- y = bx + c
- b = slope ; c = intercept
Taking the pair of points on the graph;
The slope = Change in y / Change in x
Now we have ;
Slope = (0 - 5) / (5 - 0) = -5/5 = -1
The intercept value can be obtained from the graph; which is the value of y when x = 0
Now the equation becomes ;
