slope $=-4$

The points are :
$(7,18) = color(blue)(x_1,y_1$
$(11,2) = color(blue)(x_2,y_2$

The slope is found using formula
slope $=(y_2-y_1)/(x_2-x_1$

$=(2-18)/(11-7$

$=(-16)/(4$

$=-4$

The slope of a line is rise/run.

In other words, it is the change in y over the change in x.

Hence, $(2-18)/(11-7)$

The answer is $-4$

The slope of the line is $-4$

What is the slope of the line between (7,18) (7,18) and (11,2 ) (11,2 ) ?
