algebra again

Write an equation that passes through the points (4, 3) and (2, 2)
I have 2 3 is 5 and 24 is 2 so y equals 5/2x plus b. I put in 2,2 into the equation to get the y intercept, so 2 equals 5/2 times 2 plus b
5/2(2) is 10/4 reduce to 5/2
Now add 5/2 to 2
Please help, I'm stuck!!!

I think I've got it, is it
5/2 (2) is 10/2 so 5
25 is 7 so y equals 5x 7
