Find the equation of the line that contains the points (2,4) and (8,9). Write the equation in the form y=mx+b and identify m and b.
step 1
Find the slope
m=(9-4)/(8-2)
step 2
Find the equation in slope-intercept form
y=mx+b
we have
m=5/6
point (2,4)
substitute and solve for b
4=(5/6)(2)+b
4=(5/3)+b
b=4-5/3
therefore
