Equation of the graph is y = –9x + 360.
Solution:
Take any two points on the line.
Let the points are (40, 0) and (0, 360).
Slope of the line:
m = –9
The slope is –9.
y-intercept is the point where the line intersects with the y-axis.
y-intercept = 360
b = 360
Slope-intercept form:
y = mx + b
y = –9x + 360
Equation of the graph is y = –9x + 360.
