Answer to Question #186237 in Analytic Geometry for Innocent Lorita

Question

The slope of the line which passes through the point (8,14) and (0,4) is

Answer 1

Equation of line is $y=kx+c$

We know two points on this line, so we can make the system of equations:

$\begin{cases} 14=8k+c \\ 4=c \end{cases} => k=\frac{10}8=\frac{5}4$

Next, $\arctan(k) =\arctan(1.25)$.The slope is $k=\frac{5}{4}.$
