Use The Law : \[\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=m\] Where m=slope and (10,5)=(x1,y1) ....(x,9)=(x2,y2) Now fill up the Rule,and solve it .. ______ Any questions ?

Find the value of y so that so that the line passing through (4, y) and (5, 3) has a slope of 1. on this one what do i do after i get 4/4 ?

Since the x value increased by one, you need to make the y value increase by 1 in order to have a slope of 1. Therefore, you need to find a number that equals 3 when added to 1, which is 2.
