If you go from point (-1, -3) to point (4, 4), you can find the slope of the line using the slope formula. 
. So our slope is 7/5. The line goes through the y axis at -3/2, so putting that together we get an equation for the line that is 
, choice D from above.
As I understand, we need to evaluate the given rational expression, we will get that the evaluated expression is equal to - 1/10
<h3>Evaluating expressions:</h3>
Evaluating an expression just means that we need to replace the variable in the expression for a given value, here we have the expression:
And we want to evaluate it in:
So we just need to replace k by that value in the above expression, we will get:
Now we can just solve this:
