First find slope and y intercept
Slope = rate of change
Find two random points
(0,3) and (2,0)
Now use (y2-y1)/(x2-x1) to find slope
(0-3)/(2-0) = -3/2 is the slope
Now find y intercept
Y intercept is when x = 0, (0,y)
Therefore y intercept is (0,3)
Slope intercept form: y = mx + b
m = slope, b = y intercept
Answer: y = -3/2x + 3
