Answer:
I think the answer(s) are m = -3 and/or m = 1.5 because they both hit the lines.
(sorry if I'm wrong or this wasn't helpful)
Explanation:
Three ways to find the slope of a line:
1. You may have two points ( x 1 , y 1 ) and ( x 2 , y 2 ) (often one or both of these points may be intercepts of the x and/or y axes). The slope is given by the equation
y 2 − y 1

m = -------------- (<- that's supposed to be a fraction btw)
x 2 − x 1
2. You may have a linear equation that is either in the form or can be manipulated into the form
y = m x + b .
In this case the slope is m (the coefficient of x ).
3. If the line is a tangent to another function, you may have (or be able to determine) the slope of the tangent as the derivative of the function. Normally in this case the derivative is a function expressed in terms of x and you need to substitute the value of x into this function for the required location.
