Answer:
y = 4x - 57
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
y - [tex]y_{1}[/tex] = m ( x - [tex]x_{1}[/tex] )
~~~~~~~~~~~~~~~
( 15 , 3 )
( 19 , 19 )
m = [tex]\frac{19-3}{19-15}[/tex] = 4
y - 3 = 4 ( x - 15 )
y = 4x - 57
