Find the slope m of the line that passes through the points (3, –8) and (–7, –4). (Points : 5)
slope m = –5 /2
slope m = –2 /5
slope m = 2 /5
slope m = 5 /2

Question

Find the slope m of the line that passes through the points (3, –8) and (–7, –4). (Points : 5)  
       slope m = –5 /2
       slope m = –2 /5
       slope m = 2 /5
       slope m = 5 /2

anonymous · Answer

m = rise/ run = (-4-(-8))/(-7-3) = 4/10 = 2/5 
There! =D

can you show me how to do it

anonymous · Answer

yup sure. The slope is rise/run so you must find the y-value of the first point - the y value of the second point. Then divide that by the x-value of the first point - x value of second point. 

That way, you can see how much the y value changes when the x value changes by 1 which is the slope. Tell me if it doesn't make sense.
