Write an equation of the line, in the form of y = mx + b that passes through the given points.
3. (0,5),(2,0)
5. (1,4),(3,8)

slope is change in y divided by change in x
05=5=y
20=2=x
5/2 is slope
so we have y=5/2x + b
plug in the point 0,5
now we have 5=5/2(0) + b
b=5.
the same for the next problem.
