What is the equation of the line that passes through the points (0.8, 0.2) and (0.5, 1.5)

We can write the equation of line in the form

y=mx +b

where m is slope , and b is y intercept

Now the slope formula is

let's plug the points in the formula to find slope

m=

So we get equation as

Now we have to find the value of b also

to find the value of b , we can plug any one point

So the equation is

what shape is
