What is the slope of the line which passes through (4,7) and (2,3)

[tex]\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{7})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{3}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{3-7}{2-4}\implies \cfrac{-4}{-2}\implies 2[/tex]
Answer:
A. 2
Step-by-step explanation:
To solve this problem, first you have to use the slope formula of [tex]\displaystyle \frac{y_2-y_1}{x_2-x_1}=\frac{rise}{run}[/tex].
y2=3
y1=7
x2=2
x1=4
Solve.
[tex]\displaystyle \frac{3-7}{2-4}=\frac{-4}{-2}=2[/tex]
As a result, the slope is 2.
