Question

Find an equation of the line containing the given pair of points (4,1) and (12,7)

Answer 1

Y = 3/4 X -2

Explanation:

Just apply the equation of a straight line (Y=mX+C), remembering that m represents the gradient of the line. This can be found by dividing the change in the y-axis by the change in the x-axis. Then substitute a set of coordinates with your obtained gradient into Y=mX+C to obtain C, i.e. the y-intercept.
