Answer:
A) [tex]-3x+y=-7[/tex]
Step-by-step explanation:
Slope of the line:
[tex]\frac{5-(-1)}{4-2} =\frac{6}{2} =3[/tex]
[tex]y=mx+b[/tex]
[tex]y=3x+b[/tex]
Plug in x and y values of any of the points.
[tex]5=3(4)+b[/tex]
[tex]5=12+b[/tex]
[tex]b=-7[/tex]
Equation of the line:
[tex]y=3x-7[/tex]
Subtract 3x from both sides:
[tex]y-3x=-7[/tex]
[tex]-3x+y=-7[/tex]
A is correct.
