Question 48782: Given the points (x1,y1) = (2,3) & (x2,y2)= (5,9)
Find m (slope) and b (y-axis intercept) of the equation y=mx+b

You can put this solution on YOUR website!
M = (y2 - y1)/(x2 - x1) = (9 - 3)/(5 - 2) = 6/3 = 2
y = 2x + b choose a point to figure the rest
3 = 2*2 + b
3 = 4 + b
-1 = b the y-intercept is P(0,-1)
Equation: y = 2x - 1
