You can put this solution on YOUR website! if a straight line with slope 5 contains the points (1,2) and (3,k), the value of k is?
.
Given two points on a line, slope is defined as:
m = (y2-y1)/(x2-x1)
.
In your problem, they give:
two points: (1,2) and (3,k)
slope: 5
.
Plugging into:
m = (y2-y1)/(x2-x1)
5 = (k-2)/(3-1)
5 = (k-2)/(2)
10 = k-2
7 = k
