Answer:

slope = 1.5 , y-intercept = 12 , equation = y = 1.5x + 12

Step-by-step explanation:

  1. here we can see the line intersecting the y-axis at 12. this is y intercept.
  2. to find slope: find two best coordinates: ( 0 , 12 ) , ( 4 , 18 )
  • now use the formula to find slope:
    (y2-y1)/(x2-x1)

:
(18 - 12)/(4 - 0 )

:
(6)/(4)


1.5 is the slope of the line

  • equation formula: y = mx + b .......where m is slope and b is y intercept

y = 1.5x + 12
