A line passes through the point (-1,-3) and has a slope of 1. Write an equation for this line

Question

im in a math class and need help thanks

Answer 1

Using point-slope formula (y -y₀) = m(x - x₀)

 

y - (-3) = (1) [x - (-1)]

y + 3 = x + 1

y = x - 2

Answer 2

This problem supplies the two requirements for the point-slope form of the equation of a line:

 

The equation of a straight line in the form y-y₁= m (x-x₁), where m is the slope of the line and (x₁, y₁) are the coordinates of a given point on the line.

 

Plug in the values:

    (y - (-3)) = (1)(x - (-1))

     y + 3 = x + 1

     y = x - 2              [this is answer in slop-intercept form]

     x - y = 2              [ this is answer in Standard From]
