Question 42364: Image Hosted by Free image hosting

How can I find the slope of the lines graphed in this.. Isn't it like -y 7

The x and y-axes intercepts are -2.5 and 5 respectively.

See my solution to this problem

Thus we can write the equation of the straight line as
x%2F%28-2.5%29%2By%2F5+=+1
or -2x+%2B+y+=+5
or y+=+2x+%2B+5

Comparing with the equation y+=+mx+%2B+c, here m = 2 (slope), c = 5 (intercept on y-axis).
So slope = m = 2.
