Question

a student finds the slope of a line between (14,1) and (18,17) . she writes 1-17/18-14 what mistake did she make find the correct slope between these two points and show all work

Answer 1

I'm not going to give you the answer (that's cheating...) but I will give you hints :) The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent

Answer 2

Hello !!

For you find the correct result, you can make use of this formula.

m = (yB - yA)/(xB - xA)

Now, you have knowlegde of the formula, you only put the informations of the statement in the formula.

m = (yB - yA)/(xB - xA)

m = (17 - 1)/(18 - 14)

m = 16/4

m = 4

Final result : 4 is the slope.

I hope I have collaborated !
