What is the slope of a line that passes through (10,-5) and (18,11)?
\[m=\frac{ y _{2}-y _{1} }{x _{2}-x _{1} }\]
Use this equation; just sub in the the coordinates
as given above, you have m = y2 - y1 over x2 - x1. and what that means is just filling in your numbers. since x comes before y 10 would be your first x and - 5 would be your first y. 18 is your second x 11 is your second y. then you divide and simplify your answer if possible.
