Mathematics: The formula is used in economics to determine the impact on gross domestic product (gdp) x by increasing government spending by d dollars if the proportion of additional income that people spend is h. (a) solve the formula for h. (b) find h if the government increased spending by $400 billion and gdp increased by $4000 billion.

$y = - \frac{1}{2} x + 2$

solution,

From the observation of graph

take any two points on this graph.

(X1,y1)-->(4,0)

(x2,y2)--->(0,2)

Now,

$slope(m) = \frac{y2 - y1}{x2 - x1} \\ m = \frac{2 - 0}{0 - 4} \\ m = \frac{2}{ - 4} \\ m = - \frac{1}{2} \\$

The slope intercept form is y=mx+c

where,m= slope and c=y-intercept

$y = - \frac{1}{2} x + c - - \: (i)$

$c = y1 + \frac{1}{2}x1 \\ c = 0 + \frac{1}{2} \times 4 \\ c = 2$

Therefore,

The required equation of line is:

$y = - \frac{1}{2} x + 2$

hope this helps...

Good luck on your assignment...
