Question

Find the equation of the line. Use exact numbers. y = __x + __

Answer 1

Answer:

y   = 3x+3

Step-by-step explanation:

We know the y intercept since it crosses the y axis at (0,3) and we know the x intercept since it crosses the x axis at (-1,0)

We can fidn the slope

m = (y2-y1)/(x2-x1)  (0,3) (-1,0)

     =(0-3)/(-1-0)

     = -3/-1

      =3

The equation for the line is in the form

y = mx +b where m is the slope and b is the y intercept

y   = 3x+3
