What is 23 over 18 in simplest form

tatuchka [14]

$\frac{23}{18}$ is already in simplest form because 23 is a prime number, which means that it is only divisible by 1 and itself (23). Hope this helps! :)

A line passes through the points ( − 16 , 14 ) and ( 8 , 35 ) . Calculate the slope of the line - simplify answer if possible. (

REY [17]

Given two points $(x_1,y_1),\ (x_2,y_2)$ , the slope of the line connecting them is defined as

$m=\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}$

In your case, the points are

$(x_1,y_1)=(-16,14),\ (x_2,y_2)=(8,35)$

Plugging these values in the slope formula gives

$m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{35-14}{8-(-16)}=\dfrac{21}{24}=\dfrac{7}{8}$
