#(y-16) = -5/21(x-60)#

First you determine the slope:

#(color(blue)(x_1),color(blue)(y_1)) = (60,16)#

#(color(red)(x_2),color(red)(y_2))=(18,26)#

#color(green)m =(color(red)(y_2)-color(blue)(y_1))/(color(red)(x_2)-color(blue)(x_1))#

#color(green)m =(color(red)(26)-color(blue)(16))/(color(red)(18)-color(blue)(60))=-5/21#

Now use the Point Slope form of a line:

#(y-color(blue)(y_1)) = color(green)m(x-color(blue)(x_1))#

#(y-color(blue)(16)) = color(green)(-5/21)(x-color(blue)(60))#

graph{(y-16) = -5/21(x-60) [-67, 93, -0.96, 79.04]}
