Find the equation
step 1
Find the slope
we take two points
(16,150) and (62,200)
m=(200-150)/(62-16)
m=50/46
step 2
Find the equation in point slope form
y-y1=m(x-x1)
we have
m=50/46
(x1,y1)=(16,150)
substitute
y-150=(50/46)(x-16)
Convert to slope intercept form
y=mx+b
Isolate the variable y
y-150=(50/46)x-17.39
y=0.11x-17.39+150
y=0.11x+132.61the variable y
y-150=(50/46)x-17.39
