Question

How do you find a standard form equation for the line with x-intercept of -3 and passes through the point (-3, 7)?

Answer 1

`color(indigo)(7x - 3y = -21, " is the equationof the line"`

Explanation:

`"Given x-intercept " = -3, (x_1, y_1) = (-3,7)`

`"Equation is given by " (x/a) + (y/b) = 1, " where a and b are the x and y intercepts"`

`"x-intercept "= -3, " y-intercept " = 7`

`:. The equation is (x/-3) + (y/7) = 1`

`color(indigo)(7x - 3y = -21, " is the equationof the line"`
