To find the equation of the line that passes through the points (2, 4) and (0, 1), we have to find the slope of the line using the rule


m=(y_2-y_1)/(x_2-x_1)

Let x1 = 2 and y1 = 4

Let x2 = 0 and y2 = 1


\begin{gathered} m=(1-4)/(0-2) \\ m=(-3)/(-2) \\ m=(3)/(2) \end{gathered}

The form of the slope-intercept is


y=mx+b

b is the y-intercept (value y at x = 0)

Since at x = 0, y = 1

Then the y-intercept is 1

b = 1

The equation is


y=(3)/(2)x+1

The slope is 3/2
