Explanation:
#"to calculate the slope m use the "color(blue)"gradient formula"#
#•color(white)(x)m=(y_2-y_1)/(x_2-x_1)#
#"let "(x_1,y_1)=(-7,11)" and "(x_2,y_2)=(9,-10)#
#rArrm=(-10-11)/(9-(-7))=(-21)/16=-21/16#
Explanation:
First we find
Where
Now we just plug it in, giving us
Now that we have
The line formula is
Now we add
Now we find a common denominator between the constants
