To find the slope of the line you have to do change in y over the change in x. I will be using the example (3,6) and (1,4). So if you find the change in y over the change in x you have 2/2. The slope would be 1. and if you have slope intercept form (y=mx+b) you get y=1x+b. Now all you have to find is b. Substitute in any of the points given and you have 4=1+b. Therefore b = 3. So your full equation is: y=x+3
Area= length(width) 1/5=1/3(length) Length= 1/5(3/1) or 1/5 divided by 1/3 Length= 3/5 cm Therefore, the length of the rectangle is 3/5 cm. Hope this helps!
