HELP HELP HELP HELPPPPPPPPPPPP ANYONE PLEASE? What is the equation in standard form of the line which passes through (1, −3) and has a slope of 2? 2x − y = 5 2x − y = −5 2x + y = 5 2x + y = −5

OpenStudy (larseighner):

Use the point slope formula \( y - y_0 = m(x - x_0) \) where m is the slope and the point is \( (x_0, y_0) \)

OpenStudy (jenniferjuice):

X - X?

OpenStudy (jenniferjuice):

@LarsEighner hello?

OpenStudy (larseighner):

Can you plug into the point - slope formula given above. Replace the m with the slope you are given. Replace \(x_0\) with the x coordinate of the point you were given. Replace \(y_0\) with the y coordinate of the point you were given.

OpenStudy (jenniferjuice):

whats x0?

OpenStudy (larseighner):

You were given a point. (1, −3) \(x_0\) is the x coordinate. \(y_0\) is the y coordinate.

OpenStudy (jenniferjuice):

yeah i do now thanks :)
