Line passes through (-3,1) has slope of 6.

Question

Write (-3,1) slope of 6 as a equation for this line

Answer 1

If (x₁, y₁) is a point on a line and if the slope of the line is m, then an equation of the line is:  y - y₁ = m(x - x₁)

So, using the given point and slope, an equation of the line is:

 

     y - 1 = 6[x - (-3)]

 

     Simplifying, we get y - 1 = 6x + 18

 

     So, y = 6x + 19
