Answer:
y = x - 700
Explanation:
The equation of the line in slope-intercept form has the following formula:
y = mx + c
where:
m is the slope
c is the y-intercept
1- getting the slope:
To get the slope, we will need two points from the graph. I will choose (700,0) and (0,-700)
slope = (y2-y1) / (x2-x1) = (-700-0) / (0-700) = 1
The equation now is:
y = 1x + c
y = x + c
2- getting the y-intercept:
The y-intercept means the value of the y at x = 0. We can get this directly from the graph.
From the graph, we can find that:
at x = 0, y = -700
Therefore:
c = -700
Based on the above, the equation of the line is:
y = x - 700
Hope this helps :)
