Step-by-step explanation:
The equation of a line, in slope-intercept is given by:
In which is a point in the line and m is the slope.
We have these following points:
(-3,2), (0,1)
I am going to use
So
Finding the slope
The slope, given two points, is given by the change in y divided by the change in x. In this question:
Points (-3,2) and (0,1).
Change in y: 1 - 2 = -1
Change in x: 0 - (-3) = 0 + 3 = 3
So
So the equation of the line is:
Well all you are doing in adding on 10,000 so the sum should look like this,
