Question

find the value of k so that the line passing through each pair of points has the given slopea) (k ,2 ) and (11 , 14) , slope = 2b) ( 1, k) and (4 , 1) , slope = -2 c) ( 3,5 ) and ( k,9 ) slope = 1/2 d) (-1 , 4) and ( -3,k ) slope = - 1/2

Answer 1

`m=(y2-y1)/(x2-x1)`

The above equation is an expression to calculate the slope of a line that passes through the points (x1,y1) and (x2,y2).

Let's replace into this equation each pair of points that you got and then solve for k, like this:
